Question description

A spherical pot of hot coffee contains 0.75 L of liquid (essentially water) at an initial temperature of 95 oC. The pot has an emissivity of 0.60, and the surroundings are at a temperature of 20 oC. What is the coffee's rate of heat loss by radiation?

I know the answer, I just cant seem to get the work right..

The equation to use is H=dQ/dt=Ae(sigma)T^4

thanks
