A where and a cylinder have the same radius and height . The volume of the cylinder is 48 cm 3. What is the volume of the sphere?
Answers
Given:
Sphere and cylinder have same radius and height.
Volume of the cylinder = 48 cm³
To find:
The volume of the sphere.
Solution:
Radius and height of cylinder are equal.
⇒ r = h
Volume of cylinder:
[tex]V=\pi r^2h[/tex]
Substitute the given values.
[tex]48=\pi r^2r[/tex] (since r = h)
[tex]48=\pi r^3[/tex]
[tex]48=3.14 \times r^3[/tex]
Divide by 3.14 on both sides.
[tex]$\frac{48}{3.14} =\frac{3.14\times r^3}{3.14}[/tex]
[tex]$15.28=r^3[/tex]
Taking cube root on both sides, we get
2.48 = r
The radius of the cylinder is 2.48 cm.
Sphere and cylinder have same radius and height.
Volume of sphere:
[tex]$V=\frac{4}{3} \pi r^3[/tex]
[tex]$V=\frac{4}{3} \times 3.14 \times (2.48)^3[/tex]
[tex]V=63.85[/tex]
The volume of the sphere is 63.85 cm³.

Find the volume of a right circular cone that has a height of 5.3 fr and a base with a circumference of 19.1 ft. Round your answer to the nearest tenth of a cubic foot.
Answers
For this case we have that by definition, the volume of a cone is given by:
[tex]V = \frac {1} {3} * \pi * r ^ 2 * h[/tex]
Where:
r: It is the radius of the cone
h: Is the height of the cone
We must find the radius knowing that the circumference of the base of the cone is[tex]19.1 \ ft[/tex]
[tex]2 \pi * r = 19.1\\r = \frac {19.1} {2 \pi}\\r = 3.04 \ ft[/tex]
Thus, we substitute in the formula:
[tex]V = \frac {1} {3} * \pi * (3.04) ^ 2 * 5.3\\V = \frac {1} {3} * \pi * 9.25 * 5.3\\V = \frac {1} {3} * 154.0165\\V = 51.34[/tex]
Thus, the volume of the cone is: [tex]51.34 \ ft ^ 3[/tex]
Answer:
[tex]51.3 \ ft ^ 3[/tex]

10. Marvin is painting three squares shaped like
The ones below. If it takes him exactly four cans
of paint to paint square 3 and five cans of paint
To paint square 2, how many cans of paint should
he need to paint square 1?
Answers
Marvin would need 6.25 cans of paint for square 1.
Using ratio of paint used
We are given that it takes 4 cans of paint to paint square 3 and 5 cans of paint to paint square 2.
This suggests a possible ratio between the amount of paint needed for different squares. Let's assume this ratio remains constant.
If the ratio between squares 2 and 3 is r, then:
Paint needed for square 2 = 5 cans = r * Paint needed for square 3
Paint needed for square 3 = 4 cans
Solving for r: r = 5 cans / 4 cans = 1.25
Assuming the same ratio applies to square 1 and 2:
Paint needed for square 1 = r * Paint needed for square 2
Paint needed for square 1 = 1.25 * 5 cans = 6.25 cans
Therefore, Marvin would need 6.25 cans of paint for square 1.
Complete question:
Marvin is painting three squares shaped like the one below. If it takes him exactly four cans of paint to paint square 3 and five cans of paint to paint square 2, how many cans of paint should he need to paint square 1?

A word processing program requires a user to enter a 7-digit registration code made up of the digits 1,2,4,5,6,7 and 9. Each number has to be used, and no number can be used more than once. How many codes are possible?
Answers
The number of possible codes is this:
7*6*5*4*3*2*1 = 7! = 5040
Final answer:
To find the number of possible codes, we can use the concept of permutations. There are 7 digits to choose from and we need to select all of them. Therefore, there are 5,040 possible registration codes.
Explanation:
To find the number of possible codes, we can use the concept of permutations.
Since the code must be made up of 7 digits and each digit can only be used once, we can calculate the number of permutations of the 7 digits. The formula to use is nPr = n! / (n - r)!, where n is the total number of elements and r is the number of elements to be selected.
In this case, there are 7 digits to choose from and we need to select all of them.
So we plug in n = 7 and r = 7 into the formula:
nPr = 7! / (7 - 7)! = 7! / 0! = 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5,040
Therefore, there are 5,040 possible registration codes.

The 4 arches combine to for a circle, so then you can find the area of the shaded region by subtracting the area of the square from the area of the circle.
The formula for area of a circle is A=[tex]\pi[/tex]r^2
Since the radius of the circle would be 11/2 or 5.5, the area if the circle would be [tex]\pi[/tex] x 5.5^2. This equals 95.0334.
The area of the square would be 11 x 11 = 121.

After the closing of the mill, the town of Sawyerville experienced a decline in its population.
The relationship between the elapsed time, t, in years, since the closing of the mill, and the town's
population, P(t), is modeled by the following function.
P(t) = 12,000 - 2^-t/15
In how many years will Sawyerville's population be 9000?
Round your answer, if necessary, to the nearest hundredth.
Answers
Step-by-step explanation:
P(t) = 12,000 (2)^(-t/15)
9,000 = 12,000 (2)^(-t/15)
0.75 = 2^(-t/15)
ln(0.75) = ln(2^(-t/15))
ln(0.75) = (-t/15) ln(2)
-15 ln(0.75) / ln(2) = t
t = 6.23
The time it would take for Sawyerville's population to decrease to 9000 can be calculated by setting the population function equal to 9000 and solving for 't'. After a series of algebraic transformations, you can isolate 't' and calculate its value with a scientific calculator.
Explanation:To find the amount of time it will take for Sawyerville's population to fall to 9000 people, we can set up the equation: P(t) = 9000. Therefore, we have 9000 = 12,000 - 2-t/15.
To solve this equation, we first need to isolate the exponential term by subtracting 9000 from both sides, getting 3000 = 2-t/15. Then, we take the natural logarithm (ln) of both sides to remove the exponential term, resulting in ln(3000) = -t/15*ln(2). Divide both sides by -ln(2) and multiply them by 15 to find 't'. The final equation is: t = -15*ln(3000)/ln(2).
In this particular problem, you may need the help of a scientific calculator to compute the value of 't'.

Suppose that after I wrote this problem, Richard Rusczyk thought he could be more clever than I could, so he wrote his own problem. Suppose that both of our problems are in the set of 12 problems you are currently working on. If you sat down at your computer this morning and randomly loaded 4 of the 12 problems, what is the probability that both this problem and Richard Rusczyk's problem were among the four you loaded?
Answers
Answer:
P = 0.0909
Step-by-step explanation:
To know the number of ways or combinations in which we can select x elements from a group of n elements, we can use the following equation:
[tex]nCx=\frac{n!}{x!(n-x)!}[/tex]
So, if you sat down at your computer and randomly loaded 4 of the 12 problems, there are 495 different possibilities and it is calculated as:
[tex]12C4=\frac{12!}{4!(12-4)!}=495[/tex]
Then, from 495 different possibilities, there are 45 possibilities that both this problem and Richard Rusczyk's problem were among the four you loaded. This 45 possibilities are calculated as:
[tex](1C1)*(1C1)*(10C2)=(\frac{1!}{1!(1-1)!})*(\frac{1!}{1!(1-1)!})*(\frac{10!}{2!(10-2)!})=45[/tex]
Because you need to select: this problem and there is only one, the problem that Richard Rusczyk wrote and there is only one, and 2 problems from the other 10.
Finally, the probability that both this problem and Richard Rusczyk's problem were among the four you loaded is equal to:
[tex]P=\frac{45}{495}=0.0909[/tex]
A drawer contains 10 blue pens, 10 black pens, and 10 red pens. Without looking. Mr. Lopez is going to take one pen from the drawer, use it, and then put it back into the drawer. Then he is going to take another pen from the drawer to use. What is the probability of Mr. Lopez taking a red pen first and then taking a blue pen?
Answers
Answer:
1/9
Step-by-step explanation:
There are 30 pens in total, 1/3 of the pens are each the following colours: blue; black; red.
This will result in a one in three chance of picking up a red pen. As Mr.Lopez puts the pen back, the fractions stay the same as it's the same possibility both times.
As it's again a one in three chance, we just have to multiply it for the possibility of him picking a blue pen, which is 1/3.
1/3 * 1/3 = 1/9

Maria is painting a mural on a brick wall. She is painting 4 circles with radii of 2 inches, 4 inches, 9 inches, and 14 inches. How much paint will she need to fill in all four circles?
She will need ____? square inches of paint for all the circles.
Answers
Answer:
932.58 in ^ 2 is needed
Step-by-step explanation:
What we need to do is calculate the area of all the circles and add it up, so we know how many square inches of paint are going to be needed.
We know that the area of a circle has the following formula:
A = pi * r ^ 2
there are 4 circles:
radio of 2 inches:
A = 3.14 * 2 ^ 2 = 12.56 in ^ 2
radio of 4 inches:
A = 3.14 * 4 ^ 2 = 50.24 in ^ 2
radio of 9 inches:
A = 3.14 * 9 ^ 2 = 254.34 in ^ 2
radio of 14 inches:
A = 3.14 * 14 ^ 2 = 615.44 in ^ 2
12.56 + 50.24 + 254.34 + 615.44 = 932.58
a total of 932.58 in ^ 2 is needed
