The surface area of a sphere with diameter d is given by the formula A = 4πr^2, where r is the radius of the sphere. Since the diameter is 30 inches, the radius is half of that, which is 15 inches.
Using the formula, we can calculate the surface area:
A = 4π(15)^2
= 4π(225)
= 900π in.²
So, the surface area of the sphere is 900π in.².
