If r=4 units and x = 8 units then what is the volume of the cylinder shown above use 3.14 for TT and round your answer to the nearest hundredth
Answers
Note: It does not say that x is the height, but this is the only piece of information missing without an obvious label, so I am using it as the height.
Final answer:
The volume of a cylinder with a radius of 4 units and a height of 8 units is 401.92 cubic units, calculated using the formula V = πr²h and rounding to the nearest hundredth.
Explanation:
Calculating the Volume of a Cylinder
To find the volume of a cylinder, we can use the formula V = πr²h, where 'V' represents the volume, 'r' is the radius, and 'h' is the height of the cylinder. Since you have provided that the radius (r) is 4 units and the height (x) is 8 units, we can substitute these values into the formula as follows:
V = 3.14 × (4 units)² × 8 units
First, we calculate the radius squared (4 units)²:
(4 units)² = 16 units²
Now we multiply this by the height and π as given:
V = 3.14 × 16 units² × 8 units
V = 3.14 × 128 units³
V = 401.92 units³
Therefore, the volume of the cylinder is 401.92 cubic units, rounded to the nearest hundredth.

A triangle's interior angles also measure 180º.
The angle measuring 130º is complementary to the corresponding interior angle, so that interior angle plus 130 has to equal exactly 180º.
180 - 130 = 50º
45 + 50 = 95º, so subtract that from 180 to find the measure of the last interior angle of the triangle.
180 - 95 = 85º
That angle of 85º is complementary to the other outside angle, n, and to find that subtract 85 from 180.
180 - 85 = 95º
n = 95

A spinner that has 4 equal parts that are the colors blue, green, red, and yellow. The spinner is spun 12 times. It lands on blue 1 time.
Part A) What is the experimental probability of the spinner landing on blue?
Part B) Compare the experimental and theoretical probabilities of the spinner landing on blue. If the probabilities are not close, explain a possible reason for the discrepancy.
Answers
Answer:
The experimental probability would be 1/12 and the theoretical probability would be 1/4. The probabilities were not close so a possible reason for the discrepancy would be the blue color on the spinner was slippery.
Step-by-step explanation:
So to start out you need to find out the experimental probability. If the spinner landed on blue 1 time out of 12 different times, you write that as a fraction of 1/12. So 1/12 is the experimental probability. It also asks for the theoretical probability. There are 4 parts of the spinner so 4 is the denominator, one of those possibilities is the one we want so 1 is the numerator, so the theoretical is 1/4. The probabilities were not close so a possible reason for the discrepancy would be the blue color on the spinner was slippery.
Just to tell you what theoretical and experimental probabilities mean is that the theoretical is the possible outcome before you do it. Experimental is where you judge your probability off of past events.
A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π meters. What is the area of the cross section?

Half of this is the radius r = d/2 = 18/2 = 9
The radius is 9 meters
Use the value of r to find the area of the circle
A = pi*r^2
A = pi*9^2
A = pi*81
A = 81pi
The area of the circular cross section is 81pi square meters
please help Use the expression 8a + 16c.
Part A
Factor the expression using the GCF.
A. 2(4a + 8c)
B. 4(2a + 4c)
C. 8(a + 2c)
D. 16(12a + c)
Part B
What is the value of the expression when a = –5 and c = –1? Enter your answer in the box.
Answers
C. 8 (a + 2c)
Explanation:
The answer is c because when you have this equation (below) you have find what both numbers are divisible by:
[tex]8a + 16c[/tex]
Both of these numbers are divisible by 8 (This number would be on the outside of the parenthesis).
[tex] \frac{8a}{8} + \frac{16c}{8} [/tex]
Now that you know they're both divisible by 8 you can start to put together your equation. So far you should have this:
8 (? +?)
Now to find the other numbers you have to think... what number multiplied by 8 will make it equal to 8a? The answer would be a. 8 times a = 8a. (Another way to do this is to just divide 8a by 8 same with 16)
Now your equation should look like this:
8 (a + ?)
Now do the same thing with the 16c as you did with the 8a. (either divide 16c by 8 or think of a number times 8 that will make it equal 16c) For this one I'm going to use the division method - so what is 16c ÷ 8? 16 ÷ 8 = 2 and finally just add the c. So your answer is 2c.
Your equation should not look like this:
8 (a + 2c)
You're done!
Part B.
-56
Eplanation:
To find this just plug in the numbers into the equation. a = -5 and c = -1.
For this I used the original equation :
[tex]8a + 16c[/tex]
Plug in the numbers....
[tex]8( - 5) + 16( - 1)[/tex]
And solve!
[tex] - 40 + - 16[/tex]
And finally....
[tex] - 40 + - 16 = - 56[/tex]
So the value of the equation if a were -5 and c were -1 would be -56!
The required expression is C. 8(a + 2c) and value of the expression when a = –5 and c = –1 is -56.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given the expression is
8a + 16c.
To find the Factor form of the given expression by using GCF.
We have,
8a + 16c.
Factors of each term:
8a = 2 x 2 x 2 x a
16c = 2 x 2 x 2 x 2 x c
The common factors are 2, 2 and 2. then Taking out the greater common factor (GCF) in the given expression;
GCF = 8
The answer is C. 8(a + 2c)
when a = –5 and c = –1
Then;
8(a + 2c)
8(-5 + 2(-1)) = 8 (-7) = -56

The measurement of angle A in the given cyclic quadrilaterals, is 135°
What is a cyclic quadrilateral?A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. It is also sometimes called inscribed quadrilateral.
Given that, a quadrilateral ABCD is inscribed in a circle, so this type of quadrilaterals are called cyclic quadrilaterals, m ∠ A = 3x+6 and m ∠ C = x+2
We need to find, m ∠ A,
We know that in cyclic quadrilaterals, the opposite angles are supplementary,
Therefore,
m ∠ A + m ∠ C = 180°
3x+6+x+2 = 180°
4x+8 = 180°
4x = 172°
x = 43°
Therefore,
m ∠ A = 3x+6
m ∠ A = 3(43)+6
m ∠ A = 135°
Hence, the measurement of angle A in the given cyclic quadrilaterals, is 135°

You have $85 in your bank account. Each week you plan to deposit $7 from your allowance and $25 from your paycheck. The equation bequals85plus(25plus7)w gives the amount b in your account after w weeks. How many weeks from now will you have $275 in your bank account?
Answers
number of weeks = 6 weeks
Explanation:
You initially have $85
Each week (w), you will deposit $7 in addition to $25
This means that the equation representing the amount (b) in the account will be:
b = 85 + (7+25) w
b = 85 + 32w
Now, we want to know in how many weeks will the amount saved be equal to $275.
To get the number of weeks, we will simply substitute with b = $275 in the above equation and solve for w as follows:
b = 85 + 32w
275 = 85 + 32w
275 - 85 = 32w
190 = 32w
w = 5.9 which is approximately 6 weeks.

You sell lemonade for $2 per cup and orange juice for $3 per cup. You sell a total of 100 cups for $ 240. How many cups of lemonade and orange juice were sold ?
Answers
240/3 = 80 cups of orange juice
From the given information,you can write an linear equation like this:
$2x + $3(100 - x) = 240
First, you have to distribute them = 2x + 300 - 3x
Then, you have to add like terms = 1x + 300=240
Next, you have to transpose 300 to the left = -1x = 300 - 240
So, you have to subtract = -1x = -60
And, you solve = -60 = -60 So x = 60
60 cups of lemonade sold
Orange:
100 - x = 100 - 60 = 40 cups of orange juice sold
So you can check our answer by using the original linear equation
2x + 3( 100 - x) = 240 2(60) + 3 (100 - 60) = 240 120 + 3(40) = 240 120 + 120 = 240 240 = 240
