The diameters of the Sun and earth are 1.4 × 10⁹ meters and 1.275 × 10⁷ respectively. Compare them

Open in App

Solution

Diameter of the Sun = 1.4×109m
Diameter of the Earth = 1.2756×107m
For comparison, we have to change both diameter in same powers of 10 i.e. 1.2756×107=0.012756×109
Hence, if we divide diameter of Sun by diameter of Earth, we get

1.4×1090.012756×109=110

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