Question

Please help!! The formula to find the period of orbit of a satellite around a planet is T^2=(4 pi^2/GM)r^3 where r is the orbit’s mean radius, M is the mass of the planet, and G is the universal gravitational constant. If you are given all the values except r, how do you rewrite the formula to solve for r?

Answer 1

t^2 = 4pi^2/gm r^2
(just a recap, its 4 times pi squared, over gm, times r squared. Hope this helps :)
