\fWe know that the moon orbits the earth. The orbital period of the moon is 2?.32 days, and the distance from the moon to the earth is 384,000 km, We wish to use this to compute the size ofthe orbit of geosynchronous orbits. {A geosynchronous orbit is one for which the orbital period is 1 day.} So we know 1'] = 384, 000 km. T1 = 27.32 days, and T3 = 1 day Plug in those values in the formula from Kepler's 3rd law of planetary motion, and solve form. Note that you will need to watch out for units: you can use whatever unit you want, so long as you are consistent
