Exercise48

A cylinder’s volume is $$960\pi$$ cubic centimeters. Its height is $$15$$ centimeters. Suppose we wanted to find how long is the cylinder’s radius. A cylinder’s volume formula is

\begin{equation*} V=\pi r^2h \end{equation*}

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:

\begin{equation*} 960 \pi=\pi r^2(15) \end{equation*}

Check whether $$64$$ is a solution for $$r$$ of this equation.

• Yes

• No
