Calculate the surface area of the cylinder below. 1. The radius of the bottom is 5cm, and the height is 15cm,
3.14 * 5 * 5 = 78.5 square centimeter (bottom area)
2 * 3.14 * 5 = 31.4cm (bottom perimeter)
31.4 * 15 = 471 square centimeter (side area)
78.5 * 2 = 471 = 628 square centimeter (surface area)
