Question

Find the surface area and volume of a sphere that has a radius of
57
57 inches. Use 3.14 for π. Do not round your answer.

Answer 1

Surface Area = 4πr^2
Surface Area = 4 * 3.14 * 57^2
Surface Area = 4 * 3.14 * 3249
Surface Area = 40670.64 square inches

Volume = 4/3 * π * r^3
Volume = 4/3 * 3.14 * 57^3
Volume = 4/3 * 3.14 * 185193
Volume = 972650.04 cubic inches

Therefore, the surface area of the sphere is 40670.64 square inches and the volume is 972650.04 cubic inches.
