Stefan-Boltzmann Law |

From florence:
Hi-
I have a college tutor and we are stumped with this question.
Assuming a filament in a 100 W light bulb acts like a perfect blackbody, what is the temperature of the hottest portion of the filament if it has a surface area of 6.3 X 10^-5 m^2? The Stefan-Boltzmann constant is 5.67 X 10-4 W/(m^2 X K^2.\
Thank you for your help. If you can only answer one question per day please answer this one and guide me through a solution.
