Question

Find th volume of a cylinder if it has a diameter of 8 and a height of 12.leave your answer in tern of pi

Answer 1

`\large\boxed{V=192\pi}`

Explanation:

The formula of a volume of a cylinder:

`V=\pi r^2H`

r - radius

H - height

We have a diameter d = 8 → d = 2r → 2r = 8 → r = 4

and H = 12.

Substitute:

`V=\pi(4^2)(12)=\pi(16)(12)=192\pi`
