If the volume of a cylindrical can is 36 times pi the height of the can is 4 then what is the radius of the can?

The formula for volume is V=pi*r^2*h, if I would plug in your numbers, the formula would look like V=pi*36*4. In order to find the height I was just need to find the square root (the opposite of squaring a number) of 36, which is 6, so the radius of the can is 6.
