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
