You can put this solution on YOUR website!
If volume is 3000(pi), we can find the radius for the surface area...we have
V+=+%284%2F3%29%28pi%29r%5E3
and
A+=+4%28pi%29r%5E2
so that
3000%28pi%29+=+%284%2F3%29%28pi%29r%5E3
3000+=+%284%2F3%29r%5E3
2250+=+r%5E3
and
r = 13.1
Now
A+=+4%28pi%29%2813.1%29%5E2+=+686.6%28pi%29 square units
