Final answer:

The surface area of the rubber ball with a diameter of three inches is approximately 28.27 square inches.

Step-by-step explanation:

To find the surface area of a rubber ball, you need to know the formula for the surface area of a sphere. The formula is:

Surface Area = 4πr^2

Where r is the radius of the sphere.

In this case, the diameter of the ball is given as 3 inches. The radius is half of the diameter, so the radius is 1.5 inches.

Plugging this value into the formula, we get:

Surface Area = 4π(1.5)^2

Surface Area ≈ 28.27 square inches

Therefore, the correct answer is C. 28in^2
