please show all steps, will rate question class is heat transfer

1. Black bears drop their body temperature from 38 C to 31 C when they hibernate. A bear lives inside a cave that has a wall temperature of -5 C and the temperature of air inside the cave is 3 C. The convection heat transfer coefficient between the bear and air is 6 W/m.C and the emissivity of bear is 0.95. Calculate the heat losses per unit area (W/m?) from the bear before and during it hibernates. (50 points)
