Answer:

V = 3078.76 in³

Explanation:

To find the volume of a cylinder, use this formula:

V = πr²h

  • V = volume
  • r = radius
  • h = height

Plug in the values you know.

V = π(7)²(20)

First let's evaluate the exponent.

7² = 49

V = π(49)(20)

Now let's multiply.

49 • π = 153.938

153.938 • 20 ≈ 3078.76

V = 3078.76 in³

This is your answer.

Hope this helps!
