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

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

Divide both sides by


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).

Take the cube root of both sides

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

Plug in r=15.5

The second choice is your answer.
