The surface area of a sphere can be calculated using the formula A = 4πr^2, where r is the radius of the sphere.
Since the diameter is given, we can find the radius by dividing the diameter by 2: r = 30 / 2 = 15 inches.
Now we can substitute the value of r into the formula to calculate the surface area:
A = 4π(15^2) = 4π(225) = 900π in.^2
Therefore, the surface area of the sphere is 900π in.^2.
