Question

radius of the earth is 6400km and that of Mars is 4300000m whose radius is bigger and by how much​

Answer 1

Answer:

Step-by-step explanation:

Radius of earth = 6400 km =6400 × 1000 m ( 1km = 1000m)

So radius of earth = 6400000m

And radius of Mars = 4300000m

So radius of earth is bigger by 2100000m

Answer 2

Answer:

Step-by-step explanation:

Radius of Earth = 6400km = 6400000m [1 km = 1000m]

Radius of Mars = 4300000 km

6400000 km > 4300000km

Therefore, Radius of Earth > Radius of Mars.

Hence, the radius of earth is greater than that of Mars.
