It is a well known fact that during a total solar eclipse the disk of the moon almost completely covers the disk of the Sun. If the distance of the moon from the earth is $3.48 \times 10^8 m$ and the distance of sun from the earth is $ 1.496 \times 10^{11} m$, determine the approximate diameter of the moon.
