Chapter 12.3, Problem 5WE

To determine

To calculate: The value of r

Answer to Problem 5WE

The value is $r=4$ units

Explanation of Solution

Given information: Consider the given information,

Volume of cylinder is = $64\pi$

And $r=h$

Formula used: Consider the given formula,

r = radius, h = height

Volume = $\pi r^{2}h$

Calculation : Consider the given information the formula is,

Volume = $64\pi$

Volume = $\pi r^{2}h$

  $\pi r^{2}h$ = $64\pi$

  $\pi r^2\times r=64\pi$

  $\pi r^3=64\pi$

  $r^3=64$

  $r=4$ units
