If a cup of coffee has temperature 94'C in a room where the ambient air temperature is 17'C, then, according to Newton's Law of Cooling, the temperature of the coffee after t minutes is T(t) = 17 + 77e /". What is the average temperature of the coffee during the first 20 minutes? average temp = =CFind the volume of the solid generated by revolving the region bounded by the graphs of the equations I +9 y= 0 around the line = = 6.
