Find the surface area of a sphere with a diameter of 30 inches. Leave your answer in terms of pi.
The formula for the surface area of a sphere is given by 4πr^2, where r is the radius of the sphere.
Given that the diameter of the sphere is 30 inches, we can find the radius by dividing the diameter by 2.
r = diameter/2 = 30/2 = 15 inches
Substituting the value of the radius into the formula, we have:
Surface area = 4π(15^2) = 4π(225) = 900π
Therefore, the surface area of the sphere is 900π square inches.
