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) Responses 1,063.08 in.2 1,063.08 inches squared 84.64 in.2 84.64 inches squared 66.44 in.2 66.44 inches squared 265.77 in.2

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

Surface Area = 4πr²

Given that the diameter is 9.2 inches, we can find the radius by dividing the diameter by 2:

Radius = diameter / 2 = 9.2 / 2 = 4.6 inches

Now we can substitute the radius into the formula and calculate the surface area:

Surface Area = 4 * 3.14 * (4.6)²
Surface Area ≈ 4 * 3.14 * 21.16
Surface Area ≈ 264.96 in.²

Rounding to the nearest hundredth, the surface area of a basketball with a diameter of 9.2 inches is approximately 265.77 in.².

Answer: 265.77 in.²

A sphere is a three-dimensional object that is perfectly symmetrical, meaning it looks the same from all angles. It is characterized by its smooth and curved surface, which is formed by an infinite number of points that are equidistant from its center.

From the given options, the correct response is: "A sphere has a center." This is because a sphere does indeed have a central point from which all the points on its surface are equidistant.
