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 formula for the surface area of a sphere is given by A = 4πr^2, where r is the radius of the sphere.
Given that the diameter of the sphere is 40 inches, we can calculate the radius by dividing the diameter by 2:
r = 40 inches / 2 = 20 inches
Now substitute the radius into the formula for surface area:
A = 4π(20 inches)^2
A = 4π(400 square inches)
A = 1600π square inches
Therefore, the surface area of the sphere is 1600π square inches.
