Question

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

Answer 1

Radius of Earth(Re) is 6400 km
And that of Mars(Rm) is 4300000m or 4300km
Now,Dividing radius of Earth to the radius of Mars :
Re/Rm = 6400/4300 = 1.488

So, Re = 1.488 Rm

Answer 2

Answer:

earth by 2100000

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
