Solution
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.
