Answer 1

C. 7 cm

Explanation:

`\boxed{\left\begin{array}{ccc}\text{\underline{Volume of a Cylinder:}}\\\\V=\pi r^2h\end{array}\right}`

Given:

`V=63 \pi \ cm^3\\\\r=3 \ cm\\\\h=?? \ cm`

Plug in the values we know into the formula and solve for "h"

`V=\pi r^2h\\\\\Longrightarrow 63 \pi= \pi(3)^2h\\\\\Longrightarrow 63 = 9h\\\\\therefore \boxed{h=7 \ cm}`

Thus, C is the correct option.
