Find the surface area of a sphere with a diameter of 30 m. Leave answers in terms of pi.

Since 4 (pi) r^2 is the equation for the surface area of a sphere, we can easily plug in the radius value of 15 (half the diameter, 30). Now, we have 4 (15^2) (pi). This can be multiplied to get a final answer of 900 (pi).

The answer is 3600pim^2
