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