What do you mean? An equation for the temperature, or radiated power?

1. A star in the main series. Explain how the radiated power, surface temperature, lifetime and location in the HR diagram depends on the star's mass. 2.E = 1/4Pi*r^2 (I think, need help with this) 3.I know that the lifetime of the star depends on its mass because of the fusion process, or how...
