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 of a sphere can be found using the formula A = 4πr², where r is the radius of the sphere. In this case, the diameter is given as 40 inches, so the radius is half of that, or 20 inches. Substituting 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.
