Question

Use the formula for the surface area of a sphere to find the surface area of a basketball that has a diameter of 9.2 inches. Use 3.14 pi and round your answer to the nearest hundredth, if necessary.(1 point)

Answer 1

The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere.

Given that the diameter of the basketball is 9.2 inches, the radius (r) is half of the diameter, which is 4.6 inches.

Therefore, the surface area of the basketball is:
4 * 3.14 * (4.6)^2
= 4 * 3.14 * 21.16
= 265.6 square inches

So, the surface area of the basketball is 265.6 square inches.
