The surface area of a soup can represents the total area of the can's exterior and may be found by the formula S.A. = 2πrh + 2πr2. A soup company designing its own cans wants to determine the height of its cans with a given surface area and radius.

Help the company by solving the surface area formula for h.

Question

The surface area of a soup can represents the total area of the can's exterior and may be found by the formula S.A. = 2πrh + 2πr2. A soup company designing its own cans wants to determine the height of its cans with a given surface area and radius. 

Help the company by solving the surface area formula for h.

anonymous · Answer

Probably the first step is
SA = 2 pi r ( h + r )

anonymous · Answer

my answers are 
h= 2 pi r/SA+2 pi r
h= 2 pi r/SA-2 pi r
h= SA+2 pi r/2 pi r
h=SA-2 p r/2 pi r

anonymous · Answer

I made a little mistake above. 
S.A. = 2πrh + 2πr^2
2πrh = SA -  2πr^2
h = SA/2πr  + r
None of the answers looks correct.
