Surface Area:
A = 4 * pi * r^2
A = 4 * 3.14 * 42^2
A = 4 * 3.14 * 1764
A = 22,179.36 square inches
Volume:
V = (4/3) * pi * r^3
V = (4/3) * 3.14 * 42^3
V = (4/3) * 3.14 * 74088
V = 392,198.08 cubic inches
Therefore,
The surface area of the sphere is 22,179.36 square inches.
The volume of the sphere is 392,198.08 cubic inches.
