Answer: The surface area of the ball is 15.90 in².

Step-by-step explanation:

1. The ball is spherical, therefore to calculate its surface area, you must apply the formula for calculate the surface area of a sphere, which is:

SA=4r^{2}\pi

2. You can calculate the radius (r) with the diameter given in the problem, as following:

r=\frac{2.25in}{2}\\r=1.125in

3. Substitute this value into the formula. Then, you obtain that the result is:

SA=4(1.125)^{2}\pi\\SA=15.90in^{2}
