A 3-m-diameter spherical tank containing some radioactive material is buried in the ground (k = 1.4 W/m·K). The distance between the top surface of the tank and the ground surface is 4 m. If the surface temperatures of the tank and the ground are 180°C and 15°C, respectively, determine the rate of heat transfer from the tank.
