(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I'm just trying to rearrange a few equations for gravity, period, radius etc., and am a tad confused.

2. Relevant equations

(G*M)/R^2 = (4*pi^2*R)/T^2

Want to rearrange for T and R. :)

3. The attempt at a solution

I got T to a point of...

T^2 = (4*pi^2*R)*(R^2)/GM

Ithinkthat's right, but I'm sure it can be further simplified.

Any halp? :)
