17.22 A spherical ball 6 cm in diameter and 310 K is placed inside a large spherical furnace at 600 K. Estimate the diameter of the spherical furnace such that 20% of the energy emitted by the furnace reaches the spherical ball. Assume the surfaces as black. What is the net exchange of energy between the two surfaces?
