The volume of a cylinder is:
We know the V and the h, we should be able to find r:
Divide both sides by :
which simplifies to:
Find the square root of each side. (Since r is a radius we will ignore the negative solution.)
This is an exact answer. If you need a decimal approximation then use your calculator on the left side.
