A baking dish is removed from a hot oven and placed on a cooling rack. As the dish cools down to 33° C from 181° C, its net radiant power decreases to 13.3 W. What was the net radiant power of the baking dish when it was first removed from the oven? Assume that the temperature in the kitchen remains at 19° C as the dish cools down.
