S=2pi%2Ar%5E2%2B2pi%2Ar%2Ah Start with the surface area of a cylinder formula.


S=2pi%2A%283%29%5E2%2B2pi%2A%283%29%2A%288%29 Plug in r=3 and h=8.


S=2%283.14159265%29%2A%283%29%5E2%2B2%283.14159265%29%2A%283%29%2A%288%29 Replace pi with 3.14159265 (note: Use more digits of pi to get better accuracy).


S=2%283.14159265%29%2A%289%29%2B2%283.14159265%29%2A%283%29%2A%288%29 Square 3 to get 9.


S=56.5486677%2B150.7964472 Multiply.


S=207.3451149 Add.


So the surface area of the cylinder is approximately 207.3451149 square units.
