(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I guess I should point out that the volume was known, which is 100 cm.

3. The attempt at a solution

I don't see why using the chain rule compels you to take the inverse of 4∏r^2. Any help would be appreciated.

I have a feeling that the solution is something like

100 = (4pir^2)/x

but that still is not right.
