A right cylinder has a total surface area of 471 square centimeters. The radius of the cylinder is 5 centimeters. What is the height in centimeters of the cylinder?

The circular area on the top = Pi r^2. The same with the bottom.
Pi = 3.1416
Surface area = 2Pi r^2 * h
Insert the known values and solve for h.
I hope this helps.
