Suppose that a sphere with radius 5a has the same volume as a cone of radius 3a. What is the height of the cone? Give your answer in terms of a. Use the formulas v=4/3 sqrt^3 and v=1/3sqrt^2h for the volumes of a sphere and cone respectively.

First, take the radius of the sphere, and using the formula for the volume of a sphere, find its volume. Do this and show what you get.
