The surface area of a sphere can be calculated using the formula:
Surface Area = 4πr^2
Given that the diameter of the sphere is 40 inches, the radius would be half of that:
Radius = 40/2 = 20 inches
Plugging the radius into the formula:
Surface Area = 4π(20)^2
Surface Area = 4π(400)
Surface Area = 1600π
Therefore, the surface area of a sphere with a diameter of 40 inches is 1600π square inches.
