Question

Find the surface area and volume for sphere. Use 3.14 for pi. 63 inches


The surface area of the sphere is ? Square inches.

The volumes of the sphere is ? Cubic inches.

Answer 1

Surface Area:
SA = 4πr^2
SA = 4(3.14)(63)^2
SA = 4(3.14)(3969)
SA = 4(12447.66)
SA = 49790.64 square inches

Volume:
V = (4/3)πr^3
V = (4/3)(3.14)(63)^3
V = (4/3)(3.14)(250047)
V = (4)(3.14)(8334919)
V = 33339676.88 cubic inches

Therefore, the surface area of the sphere is 49790.64 square inches and the volume is 33339676.88 cubic inches.
