A 21.0-kg satellite has a circular orbit with a period of 2.37 h and a radius of 8.50×106 m around a planet of unknown mass. If the magnitude of the gravitational acceleration on the surface of the planet is 7.10 m/s2, what is the radius of the planet?

I am not sure which formula to use to find the mass and then radius of the planet :/

oops, typo haha...nevermind, I found your answer below. thanks!!!
