Question

An astronomer is trying to estimate the surface temperature of a star with a radius of 5.0 × 10^8 m by modeling it as an ideal blackbody. The astronomer has measured the intensity of radiation due to the star at a distance of 2.5 × 10^13 m and found it to be equal to 0.055 W/m^2. Given this information, what is the temperature of the surface of the star? Express your answer in kelvins to two significant digits.
