3000 = 4/3 pi * r^3
solve for r
then plug into
4 pi * r^2

Use the volume formula backwards to find the radius, then use the area formula.

Get the radius by
v=4/3Ïr^3
r=8.94580222 cm
Then get the area by
A=4Ïr^2
A=1006.058 cm^2

V = (4/3)Ïr^3
A = 4Ïr^2
r = (3V/(4Ï))^(1/3)
A = 4Ï(3V/(4Ï))^(2/3)
A = 4Ï(9,000/(4Ï))^(2/3)
A â 1005.924 cm^2
