Find the surface area of a sphere with a diameter of 40 inches. Leave your answer in terms of pi.(1 point)
The surface area is "Blank" in.2
The surface area of a sphere is given by the formula A = 4πr², where r is the radius of the sphere.
Since the diameter of the sphere is 40 inches, the radius is half of that, or 20 inches.
Plugging this value into the formula, we get A = 4π(20)² = 4π(400) = 1600π
Therefore, the surface area of the sphere is 1600π square inches.
