The surface area of a sphere formula is A = 4πr^2, where r is the radius of the sphere. The radius of the basketball is half of its diameter, so r = 9.2/2 = 4.6 inches.
Plugging this radius into the formula, we get:
A = 4(3.14)(4.6^2)
A = 4(3.14)(21.16)
A = 4(66.5824)
A = 266.33
Rounded to the nearest hundredth, the surface area of the basketball is 266.33 square inches. The closest option is 265.77, so that is the correct answer.
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.
