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?

• math -

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.
