Question

Can somebody help me ??

Answer 1

Answer: C

Explanation:

`Formula: V=\pi r^2h`

We do not have the radius, but we do have the diameter. A diameter is twice the radius, therefore we can divide the diameter by 2 in order to obtain the radius.

`(d)/(2)=(12)/(2) =6`

Plug this info into the formula.

`V=\pi r^2h\\V=\pi (6)^2(7)\\V=\pi 36*7\\V=252\pi in^3`
