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

so prove  S.A. = 2πrh + 2πr2  ?

anonymous · Answer

no give the formula they'd use

anonymous · Answer

oh solve for h

anonymous · Answer

so isolate h by dividing both sides by  2πr and the answer should be obvious after that
