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.
O 265.77 in.²
O 1,063.08 in.²
84.64 in.²
66.44 in.²

Answer 1

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

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

Plugging this into the formula:
A = 4 * 3.14 * (4.6)^2
A = 4 * 3.14 * 21.16
A = 265.77 in^2

Therefore, the surface area of the basketball is 265.77 in^2. The closest option is 265.77 in^2.
