(adsbygoogle = window.adsbygoogle || []).push({}); Derive an equation for the velocity around Earth. Satellite has no mass. Radius not given. Only period, G, and ME (earth)

G = 6.67X10^-11 nm^2/kg^2 | Earth = 5.98x10^24 kg | Period = T = 1.20x10^4s

I know I can find radius, and then find velocity. But I am supposed to derive an equation to suit the given information.

2. Relevant equations

V = √GM/r

V = 2πr / T

3. The attempt at a solution

I'm not positive about my ability to cut r from the equations and merge them?
