Find the surface area of a sphere with a diameter of 30 inches. Leave your answer in terms of pi. (1 point) 900pi*in .^ 2; 2.826pi*in .^ 2; 3, 600pi*in .^ 2; 225pi*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.
Since the diameter of the sphere is 30 inches, the radius is half of that, which is 15 inches.
Plugging that value into the formula, we get:
A = 4π(15)^2
A = 4π(225)
A = 900π
Therefore, the surface area of the sphere is 900π in^2.
So the answer is 900pi*in .^ 2.
