The formula for the surface area of a sphere is given by 4πr^2, where r is the radius of the sphere.

In this case, the diameter is given as 30 inches, so the radius would be half of the diameter, which is 15 inches.

Plugging the radius into the formula:

Surface area = 4π(15)^2
Surface area = 4π(225)
Surface area = 900π in.2

Therefore, the surface area of the sphere is 900π in.2.
