The formula for the surface area of a sphere is A = 4πr^2, where r is the radius of the sphere.
Since the diameter is 40 inches, the radius is half of the diameter, which is 20 inches.
Substitute the radius into the formula:
A = 4π(20)^2
A = 4π(400)
A = 1600π
Therefore, the surface area of the sphere is 1600π square inches.
