Find the surface area and volume for the sphere. Use 3.14 for pi. Round to the nearest hundredth. Radius of 31.5

Answer 1

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

Surface Area = 4 * pi * r^2

Given that the radius of the sphere is 31.5, we can plug in the values:

Surface Area = 4 * 3.14 * (31.5)^2
Surface Area = 4 * 3.14 * 992.25
Surface Area = 4 * 3123.675
Surface Area ≈ 12494.70

Therefore, the surface area of the sphere is approximately 12494.70 square units.

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

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

Plugging in the values:

Volume = (4/3) * 3.14 * (31.5)^3
Volume = (4/3) * 3.14 * 31185.375
Volume = (4/3) * 98370.491
Volume ≈ 130493.99

Therefore, the volume of the sphere is approximately 130493.99 cubic units.
