1. The problem statement, all variables and given/known data What is the period of revolution (in minutes) of a satellite orbiting Earth at 161000 m? 2. Relevant equations T^2 = (4*pi*r^3)/(GM) 3. The attempt at a solution Well, I plugged in the values, and got T = 5250.925844, but that's not right. T, would come out as seconds, right?
