The sun is approximated as a spherical black body with a surface temperature of 5762 K. The irradiation from the sun as measured by a pyranometer on earth's surface is 1353 W/m2. The distance from the earth to the sun is approximately 1.5x10" m. Assuming that the sun radiates evenly in all directions, estimate the diameter of the sun. Ignore effects of reflection and refraction due to earth's atmosphere.
