The large isothermal enclosure of Problem 10 is a sphere,
having a diameter of 10 m. The interior surface is smooth and completely
covered with carbon. There is a small hole, 1 cm in diameter, on the surface of
the sphere. The rate of radiant energy emitted through the small hole is 100 W.
Find the temperature of the sphere.
