To compare radii, both must be in same units.

So, let's convert kilometre$(km)$ into metre$(m)$

Radius of the Mars is $=4300000$ meters

Radius of the Earth is $=6400km=6400×1000$ meters$=6400000$ meters

Now,$6400000>4300000$

So, Earth has bigger radius as compare to mars.

and, $=6400000$ meters $−4300000$ meters $=2100000$ meters.

$=2100km$

So, the Earth has bigger radius tha mars by $2100km$
