योग

उत्तर

Diameter of the Sun = 1.4 × 109 m

Diameter of the Earth = 1.2756 × 107 m

For comparison, to change diameter in same power of 10 that is 1.2756 × 107 = 0.012756 × 109

Therefore, if we divide of sun by diameter of earth, get:

`(1.4 xx 10^9)/(0.012756 xx 10^9) = 110`

Hence, diameter of Sun is 110 times the diameter of Earth.
