Homework Statement
A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r decreases. If the length of the cylinder is increasing at 0.1 cm per second, find the rate at which the radius is changing when the radius is 1 cm and the length is 5 cm.

The Attempt at a Solution
So I know that dL/ds=0.1. But I don't know exactly how the radius changes as L changes. I'm having trouble setting up a function for this. If I had that I could do the rest of the problem.
