i got help with this problem a couple days ago. the answer and explanation given made sense to me but on my list of answers it said the the answer is suppose to be:
r=[-pih+sqrt(pi^2h^2+2piA)]/2pi

if anyone can figure out how to get that thanks so much.

the original problem is:
A=2pir^2 + 2pirh
*solve for positive r
