1.	Radius of the Earth is 6400 km and that of Mars is 4300000 m. Whose radius is bigger and by how much?
Answer» Radius of the Earth = 6400 km = 6400 × 1000 m = 6400000 m And radius of the Mars = 4300000 m ∴ Radius of the Earth is greater than the radius of the Mars by (6400000 – 4300000) m = 2100000 m.

Radius of the Earth is 6400 km and that of Mars is 4300000 m. Whose radius is bigger and by how much?

Answer»

Radius of the Earth = 6400 km = 6400 × 1000 m = 6400000 m

And radius of the Mars = 4300000 m

∴ Radius of the Earth is greater than the radius of the Mars by (6400000 – 4300000) m = 2100000 m.
