Find the surface area of a right circular cylinder

Question

Solve for h: S= 2(pie)r(squared) + 2(pie)rh 

 

Find h when S = 102ft(squared) and r= 2 ft.

Answer 1

Formula wise the answer should begin to appear from solving the equation S = 2(pi) r^2 + 2(pi)rh. Substituting and isolating h will give an answer in terms of pi.
