Determine the total rate of heat transfer from the surface

A 8-cm spherical ball whose surface is maintained at a temperature of 78oC is suspended in the middle of a room at 17oC. If the convection heat transfer coefficient is 16 W/m2-oC and the emissitivity of the surface is 0.74, determine the total rate of heat transfer from the surface.
