kirill [66]

Answer:

V = 65.19

Step-by-step explanation:

Remark

You need r. You can get it from the circumference of the circular base.

Once you have that, the formula is Area = 1/3 pi r^2 j

Givens

C = 20.236

h = 6 feet

Formulas

C = 2 pi r

Volume = 1/3 pi r^2 h

Solution

Find r from C = 2 pi r

20.236 = 2 * 3.14 * r Combine the right

20.236 = 6.28 * r Divide by 6.28

20.236/6.28 = 6.28 * r / 6.28

3.222 = r

Now that you have r, you can solve for the volume

V = (1/3) pi 3.222^2 * 6 Square r

V = 1/3 * pi * 10.381 * 6 Now multiply through by all, but pi

V = 20.762 pi

V = 65.194

Given ƒ(x) = 3x + 9, find x when ƒ(x) = 21. A) 3 B) 4 C) 7 D) 10

Alborosie

Answer:

Step-by-step explanation:

Replacing f(x) with 21, this is the equation

21=3x+9

First, subtract 9 from each side of the equation to get:

12 = 3x

Next, divide each side by 3 to get:

4 = x

So the answer is B.
