Question

2 π r2 + 2 π r h
Above is the formula for finding the surface area of a cylinder. How can that be simplified so I can find the height? In other words how can I get the "h" all by itself?

Answer 1

if A= given,r+given
A=2 π r2 + 2 π r h
then
A-2 π r2 = 2 π r h divide both sides by 2 π r to get
(A-2 π r2) /( 2 π r)= h
