the thermal conductivity of glass is 0.84 J/(s*m*C) what do i do with this

A 100-W lightbulb generates 95 W of heat, which is dissipated through a glass bulb that has a radius of 3.2cm and is 0.60mm thick. What is the difference in temperature between the inner and outer surfaces of the glass? i am completely lost and need help
