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.
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.
