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.

Please answer correctly this is for school

Answer 1

incorrect

Answer 2

still incorrect

Answer 3

The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Since the basketball has a diameter of 9.2 inches, the radius is half of the diameter, so the radius is 9.2/2 = 4.6 inches.

Now, plug the radius into the formula:

Surface Area = 4 * 3.14 * (4.6)^2
Surface Area = 4 * 3.14 * 21.16
Surface Area = 4 * 66.58
Surface Area = 265.52 square inches

Therefore, the surface area of the basketball is 265.52 square inches.

Answer 4

I apologize for the mistake in my previous response. Let's correct it.

The surface area formula for a sphere is 4πr^2, where r is the radius of the sphere. Since the basketball has a diameter of 9.2 inches, the radius is 9.2/2 = 4.6 inches.

Now, plug the radius into the formula:

Surface Area = 4 * 3.14 * (4.6)^2
Surface Area = 4 * 3.14 * 21.16
Surface Area = 4 * 66.6984
Surface Area = 266.7936 square inches

Rounding to the nearest hundredth, the surface area of the basketball is 266.79 square inches.

Answer 5

Let's correct the calculation again.

Surface Area = 4 * π * (4.6)^2
Surface Area = 4 * π * 21.16
Surface Area = 84.64π

Using 3.14 for π:

Surface Area ≈ 84.64 * 3.14
Surface Area ≈ 265.8616 square inches

Rounded to the nearest hundredth, the surface area of the basketball is approximately 265.86 square inches.
