What is the surface area of a right circular cylindrical oil can, if the radius of its base is 4 inches and its height is 11 inches?
----------------------
The area of each end is pi%2Ar%5E2
= 16pi =~ 50.265 sq inches.
------------
The lateral area (the circular part) is 2pi%2Ar%2Ah
= 88 pi =~ 276.46 sq inches.

area of can=area of top and bottom %282%2A%28pi%29r%5E2%29+ area of sides(height*circumference of base) %28%28h%29%28pi%29%28d%29%29
Area=2%28pi%294%5E2in%5E2%2B8in%28pi%29%2811in%29
Area=16%28pi%29in%5E2%2B88%28pi%29in%5E2=104%28pi%29in%5E2
ANSWER: Surface area of the can is 104%28pi%29in%5E2.
