The formula for the volume of a sphere is the following:


V= (4)/(3) \pi r^3

Plug in V=5000π and solve for the radius.


5000 \pi = (4)/(3) \pi r^3

Divide both sides by
\pi


5000 = (4)/(3) r^3

Multiply both sides by 3/4 (to eliminate the 4/3 on the right side)
Also, flip the equation so we have the unknown variable on the left side (math etiquette).


r^3=3750

Take the cube root of both sides


r \approx 15.5

Now, calculate the surface area since now we know the radius.
The formula for the surface area is the following:


S=4 \pi r^2

Plug in r=15.5


S \approx 3033

The second choice is your answer.
