###### Exercise28

A cylinder’s volume is $$704\pi$$ cubic centimeters. Its height is $$11$$ centimeters. Suppose we wanted to find how long is the cylinder’s radius. A cylinder’s volume formula is

$$\displaystyle{V=\pi r^2h}\text{,}$$

where $$V$$ stands for volume, $$r$$ for radius and $$h$$ for height. Let $$r$$ represent the cylinder’s radius, in centimeters. We can solve this problem using the equation:

$$\displaystyle{704 \pi=\pi r^2(11)}\text{.}$$

Check whether $$8$$ is a solution for $$r$$ of this equation.
