A sphere has been placed inside an cylinder with the same dimensions;both have a radius of 6cm,and a height of 12cm How many cubic centimeters of space does the sphere fill not fill up. A.432pi cm B.72 pi cm C.288 pi cm D.144 pi cm
Answer:
D
Step-by-step explanation:
Final answer:
To find the cubic centimeters of space not filled by the sphere in the cylinder, subtract the volume of the sphere (288π cm³) from the volume of the cylinder (432π cm³), yielding 144π cm³. Therefore, the correct answer is D. 144π cm³.
Explanation:
To determine how many cubic centimeters of space the sphere does not fill in the cylinder, we first need to calculate the volume of the cylinder and then subtract the volume of the sphere from it.
The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. In this case, with a radius of 6 cm and height of 12 cm, the volume is:
[tex]V_{cylinder}[/tex] = π × (6 cm)² × 12 cm = 432π cm³.
The volume of a sphere is given by the formula V = 4/3 πr³. With a radius of 6 cm, the volume is:
[tex]V_{sphere[/tex] = 4/3 π × (6 cm)³ = 288π cm³.
The space the sphere does not fill up in the cylinder is:
Space not filled = [tex]V_{cylinder}[/tex] - [tex]V_{sphere[/tex] = 432π cm³ - 288π cm³ = 144π cm³.
Therefore, the answer is D. 144π cm³.
The measure of arc BD is __.

PLEASE HELP. URGENT!! ASAP
- The measure of arc [tex]\( BD \)[/tex] is 260°.
- The measure of arc [tex]\( ADB \)[/tex] should be 320° (corrected).
- The measure of arc [tex]\( ABC \)[/tex] is 80°.
To find the measure of each arc in the circle, we need to remember that the total degrees in any circle is 360°. The diagram shows a circle with specific arcs and angles labeled.
Here are the steps to find each arc's measure:
1. Measure of arc [tex]\( BD \)[/tex]:
- Arc [tex]\( BD \)[/tex] is opposite the central angle [tex]\( \angle BRD \)[/tex], which is not directly given.
- Since [tex]\( \angle BRC \)[/tex] is 40° and [tex]\( \angle CRD \)[/tex] is 60°, then [tex]\( \angle BRD = 360° - (\angle BRC + \angle CRD) \)[/tex].
- Calculating [tex]\( \angle BRD \)[/tex] gives [tex]\( 360° - (40° + 60°) = 260° \)[/tex].
- Therefore, the measure of arc \( BD \) is 260°.
2. Measure of arc [tex]\( ADB \)[/tex]:
- Arc [tex]\( ADB \)[/tex] includes arcs [tex]\( AD \)[/tex] and [tex]\( DB \)[/tex].
- We already know [tex]\( DB \)[/tex] is 260°.
- [tex]\( AD \)[/tex] is opposite the central angle [tex]\( \angle ARD \)[/tex], which is given as 120°.
- Adding them together, the measure of arc [tex]\( ADB = \angle ARD + \angle BRD = 120° + 260° = 380° \).[/tex]
- This exceeds 360°, which suggests an error. Since [tex]\( AD \)[/tex] and [tex]\( BD \)[/tex] are parts of the circle that add up to its whole circumference, they should add up to 360°, not more. Hence, [tex]\( ADB \)[/tex] should be [tex]\( 360° - \angle BCD \)[/tex] which is 360° - 40° = 320°.
3. Measure of arc [tex]\( ABC \)[/tex]:
- Arc [tex]\( ABC \)[/tex] includes arcs [tex]\( AB \)[/tex] and [tex]\( BC \).[/tex]
- [tex]\( BC \)[/tex] is opposite the central angle [tex]\( \angle BRC \)[/tex], which is given as 40°.
- [tex]\( AB \)[/tex] is the rest of the circle not included in \( ADB \), so [tex]\( AB = 360° - \angle ADB \)[/tex].
- Since we've found an inconsistency with [tex]\( ADB \)[/tex], we should instead calculate [tex]\( AB \)[/tex] as [tex]\( 360° - (BD + CD) = 360° - (260° + 60°) = 40° \).[/tex]
- Adding \( AB \) and \( BC \), the measure of arc [tex]\( ABC = AB + BC = 40° + 40° = 80° \).[/tex]
There seems to be an error with the measure of arc [tex]\( ADB \)[/tex] as calculated before. Arcs [tex]\( AD \)[/tex] and [tex]\( DB \)[/tex] should add up to 360° because they complete the circle together. It's also worth noting that in a properly drawn circle, the sum of the measures of arcs [tex]\( BC \)[/tex], [tex]\( CD \)[/tex], and [tex]\( DA \)[/tex]should add up to 360°. If [tex]\( BC \)[/tex] is 40° and [tex]\( CD \)[/tex] is 60°, then [tex]\( DA \)[/tex] should be 360° - (40° + 60°) = 260°, not 120°. This discrepancy suggests there may be a mistake in the given information or a misinterpretation of the diagram.
To summarize, given the information provided:
- The measure of arc [tex]\( BD \)[/tex] is 260°.
- The measure of arc [tex]\( ADB \)[/tex] should be 320° (corrected).
- The measure of arc [tex]\( ABC \)[/tex] is 80°.
how do i find the area of a trapezoid (pictures provided)

Diego has a skateboard, scooter, bike and go-cart. he wants to know which vehicle, is the fastest. a friend records how far diego traveles on each vehicle in 5 seconds. for each vehicle, diego travels as fast as he can along a straight path vehicle skateboard path=90 feet scooter=1,020 bike=4,800 centimeters go kart=0.03 kilometers a.100 inches equal 245 centimeters whatis the distance each vehicle traveled in centimers? ?
Answer:
1. Skateboard: 2,743.2. Scooter: 2,590.8. Bike: 4,800. Go-cart: 3,000.
After converting all distances to centimeters, it's clear that Diego's bike traveled the furthest (4800 cm) in 5 seconds, making it the fastest.
Explanation:Understanding the speed of Diego's vehicles requires us to convert the distances all to the same unit, centimeters. First, we know that 1 foot equals 30.48 cm. Therefore, the skateboard traveled 90 feet * 30.48 cm/foot = 2743.2 cm. The scooter traveled 1020 feet, which means it traveled 1020 feet * 30.48 cm/foot = 31,089.6 cm. The bike traveled 4800 cm, so no conversion is needed for this vehicle. Lastly, 1 kilometer equals 100,000 cm, meaning the go-kart traveled 0.03 kilometers * 100,000 cm/kilometer = 3,000 cm. Now that we have all the distances in the same unit, we can compare and state that the bike traveled the furthest in 5 seconds, making it the fastest.

Have three witches each holding a broom and a spoon. Witches say witch plus witch plus witch =45. Three brooms say broom plus broom plus a broom =21 and three spoons say spoon plus spoon plus spoon = 12 then final question is a plain witch plus broom x spoon equal a ? What’s answer?
Answer:
a=43
Step-by-step explanation:
w+w+w= 45 which means 15+15+15=45
b+b+b=21 which means 7+7+7=21
s+s+s=12 which means 4+4+4=12
w+b×s= a which means 15+7×4= 43
(hope this helps)
Answer:
The answer to the question is 43
Step-by-step explanation:
Let us recall the values from the following question stated:
Three witches each holds a broom and a spoon, saying plus witch plus witch = 45
Three brooms say broom plus broom plus a broom at = 21
Three spoons say spoon plus spoon plus = 21
Now, let us find when a plain witch plus broom x spoon
Then,
Three witches = 45, resulting to 15+15+15=45
Three brooms (b+b+b) which is =21 or 7+7+7=21
Three spoons (s+s+s) is =12 or 4+4+4=12
we make use of multiplication for the witches, the brooms, and the spoons
Therefore
w+b×s= a, which is 15+7×4= 43
Examples of skew lines

An example of skew lines are the sidewalk in front of a house and a line running across the top edge of a side of a house.
Step-by-step explanation:
:D
Final answer:
Skew lines are lines that do not intersect and are not parallel. Examples include a ladder leaning against a wall, non-parallel railway tracks, and a pencil and a ruler placed randomly on a table.
Explanation:
Skew lines are lines that do not intersect and are not parallel. They are in the same plane but do not lie on the same line. One example of skew lines is a ladder leaning against a wall. The ladder and the wall are in the same plane, but they do not intersect and are not parallel.
Another example of skew lines is a pair of non-parallel railway tracks. The tracks are in the same plane, but they do not intersect and are not parallel.
Finally, a pencil and a ruler placed randomly on a table can also be considered as skew lines. They are in the same plane, but they do not intersect and are not parallel.
The water temperature required for a certain manufacturing process is 134°F. However, the process allows for a variation of 7°F in the water temperature.
If x represents the water temperature, which inequality describes the situation? What is the range of water temperatures that is allowed for this process?
Answer:
The temperature that represents a smaller value would be the one with negative eighty (or -80) degrees Fahrenheit. Although it is negative, the value of 80 does not mean it has a smaller value as to 134 degrees. It is just that the difference between the absolute values of the two show that 134 degrees Fahrenheit has a bigger value.

In a sample of voters in Harrisburg, 18 out of 25 favored creating a new shopping center. If 50,000 people vote in the next Harrisburg election, how many are likely to vote in favor of the new shopping center based on this sample?
Answer:
36,000 people are likely to vote in favour of the new shopping centre
Step-by-step explanation:
Given
Population = 50,000
Total Sample = 25
18 favoured opening a new shopping centre
Required
Likely number of people to vote in favor of the new shopping center.
First, we need to represent the sample in proportion.
Let p represent the proportion
Since 18 out of 25 are in support of opening a new center,
p = 18/25
Having solved for the proportion,the next step is to calculate the expected number of people.
This is calculated by multiplying p by the total population.
Given that population = 50,000
The expected outcome = 18/25 * 50,000
Expected outcome = 18 * 2,000
Expected outcome = 36,000
Hence, 36,000 people are likely to vote in favour of the new shopping centre
Answer:
36,000 voters
Step-by-step explanation:
Here we have a question on proportion
Proportion of voters that favored creating a new shopping center = 18/25
That is the point estimate of voters that favored creating a new shopping center = 18/25
Therefore, among 50,000 voters in Harrisburg the number of voters that are likely to vote in favor of the new shopping center, based on the point estimate of the sample is given by the following expression;
18/25 × 50,000 = 36,000 voters.
There's 6,954 cases filed with Surpreme court only 82 were chosen by Surpreme court. what percentage was decided by the court ?
Answer:
1.2%
Step-by-step explanation:
Since only 82 were chosen by supreme Court,
The total is 6954
To calculate the percentage of the case decided by the court
82/6954 ×100
8200/6954
1.179~1.2
So the final answer is 1.2%
Final answer:
The percentage of cases decided by the Supreme Court compared to those filed is approximately 1.18%.
Explanation:
To calculate the percentage of cases decided by the Supreme Court out of the total number of cases filed, we use the formula for finding a percentage: (Number of cases decided / Total cases filed) × 100. In this scenario, the Supreme Court decided 82 cases out of 6,954 cases filed.
So, the calculation would look like this:
(82 / 6,954) × 100 = (0.01179) × 100 ≈ 1.18%
Therefore, approximately 1.18% of the cases filed with the Supreme Court were decided by the court.

Answer:
To find the expression for the box, we need to simplify the equation. Let's break it down step by step:
3 (x + 1) + 9 = box
First, distribute the 3 to the terms inside the parentheses:
3x + 3 + 9 = box
Next, combine like terms:
3x + 12 = box
Now, we can compare the simplified equation to the given expressions:
3 (x + 4)
2 (x + 6) + x
4(x – 3) – x
3 (x + 1) + 9
We are looking for an expression that matches our simplified equation, which is 3x + 12. By comparing the expressions, we can see that 3 (x + 1) + 9 is the same as 3x + 12.
Therefore, the expression that can be written in the box is 3 (x + 1) + 9.

The angle of elevation from L to K measures 24°. If KL = 19, find JL. Round your answer to the nearest tenth.
Answer:
jl = 19cos24 = 17.4. jk = 19sin24 = 7.7.
Step-by-step explanation:
We have a rt. triangle; the hyp is kl
and the hor side is jl. The angle between the hor side and hyp = 24 deg.
The value of JL rounding up to the nearest tenth will be 17.36.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Angle is the measurement of rotation motion for example if you want to measure the length in rotation geometry then it is helpful.
Given that the KL = 19 units, the angle LJK = 24°
Now by a trigonometric function
cos24° = Jl/19
JL = 19 × cos24°
JL = 17.36 hence, the correct answer or the length of the JL is 17.36 units.
