Question

What is the volume of the figure in terms of pi?

Answer 1

1539.38

Explanation:

this can be figured out as an entire cylinder and then take 1/2 of that

area of a circle of 7 cm

area =
`\pi`
`7^(2)`

area = 153.938

volume = 153.938 * 20

volume = 3078.7608

and take 1/2 of that to find volume of the half cylinder

3078.7608 / 2 = 1539.38
