find the surface area of a sphere with diameter 30m. leave you answer in terms of pi

Answer 1

The radius of the sphere is half of the diameter, so it is r=15m. The surface area of a sphere is given by the formula:

SA = 4πr²

Substituting the value of r, we get:

SA = 4π(15²)
SA = 4π(225)
SA = 900π

Therefore, the surface area of the sphere with diameter 30m is 900π square meters.
