2 *pi *r^2 + 2 *pi* r *h = 408.2 square centimeters

The formula for surface area of a cylinder is

S = 2 x pi x radius x height

Assume pi = 3.1416

S = 2 x 3.1416 x 5 x 8
S = 251.328 cm^2
S = 251.3 cm^2 ===> the answer to the nearest 10th

4 * pi * r ^2 + 2 * pi * r * h = 565.5 cm^2
oops
2 * pi * r ^2 + 2 * pi * r * h = 408.4 cm^2
