I need correct and complete work on how to get these answers.

8) 76.79 days, 19.94 meters, 2.012 rads/sec, DeltaKE = 597.3 Joules, Eradiation = 33.7 MJ

8) Imagine a black disk shaped satellite in outer spaoe is at an original temp of D Celsius, mass of 250 kg, radius of 2D meters and spinning at an initial rate of 2 radsi'sec. How long will it take this satellite to reach a temperaUJre 1 degree above the temperature of the Cosmic Microwave Background 1ivhich is 2.7 Kelvin?J What is the nal radius of the disk after it has cooled down? What is the nal spin rate? Hovv much has the kinetic energy of the disk changed by? Hov.r much net heat was radiated to outerspaoe during this time? Crustal: 50:] .Ti'kg, (I = 11 X 10'5
