Stars to a good approximation are spherical and emit

Stars, to a good approximation, are spherical, and emit electromagnetic radiation from a surface of emissivity e = 1. Suppose we observe that a star radiates energy at a rate of 3.1E27 W, and we determine, from its spectrum, that its surface temperature is 8,180 K. What is the diameter (in millions of km) of this star?
