Question

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

Answer 1

To find the surface area of a sphere, you can use the formula:

Surface Area = 4 * pi * r^2

Given that pi is approximately 3.14 and the radius (r) is 63 inches, we can plug in the values:

Surface Area = 4 * 3.14 * (63)^2
Surface Area = 4 * 3.14 * 3969
Surface Area = 4 * 12443.46
Surface Area = 49773.84 square inches

Therefore, the surface area of the sphere is 49773.84 square inches.

To find the volume of a sphere, you can use the formula:

Volume = (4/3) * pi * r^3

Given that pi is approximately 3.14 and the radius (r) is 63 inches, we can plug in the values:

Volume = (4/3) * 3.14 * (63)^3
Volume = (4/3) * 3.14 * 250047
Volume = 4.186 * 250047
Volume = 1047035.342 cubic inches

Therefore, the volume of the sphere is 1047035.342 cubic inches.
