Hmm. How do I....[I am sure it's fairly simple....:)]

[Lou Lou]

I am given a sphere with S.A.= 4536 cm^2 ...I am asked to find the volume.
I know the volume and S.A. formulas, I just don't know how I find the volume given the S.A.

Any help is appreciated.

 

[Gene]

Solve the S.A. formula for the radius.
Use that radius in the volume formula.
Show your work.

 

[Lou Lou]

so, I would do 4536 cm^2 =4(3.14) r^2 and get r by itself?

Exactly!
