How do we measure the radius of a star?

[@onehourmusic5334]

WE CAN CALCULATE RADIUS OF STAR BY THE HELP OF THAT WRITTEN DOWN EQUATION. once we figure out lumonisity and temerature of star and we generally assume e=1 after that we find out area of star. from which we can easily figure out radius of star.
