Question

Radius of the earth is 6,400 km and that of Mars is 43,00,000m whose radius is bigger and by how much ?​

Answer 1

Given:-

• Radius of the earth is 6,400 km and that of Mars is 43,00,000 m.

⠀

To find:-

• Whose radius is bigger and by how much?

⠀

Solution:-

According to the question,

⠀

⇢ Radius of the Earth = 6400 km

⇢ Radius of the Earth = 6400 × 1000

⇢ Radius of the Earth = 6400000 m

⠀

And,

⇢ Radius of the Mars = 4300000 m

⠀

Now,

⇢ Radius of the Earth - Radius of the Mars

⇢ 6400000 - 4300000) m

⇢ 2100000 m

⠀

Hence,

• Radius of the Earth is greater than the radius of the Mars by 2100000 m.

Answer 2

Question

Radius of the earth is 6,400 km and that of Mars is 43,00,000m whose radius is bigger and by how much ?

Step-by-step explanation:

$radius \: of \: the \: earth \: = \: 6400 \: km$

$6400 \: \times \: 1000 \: m \: = 640000$

$and \: radius \: of \: the \: mars \: \\ = 4300000$

$radius \: of \: the \: earth \: is \: \\ greater \: than \: the \: \\ radius \: of \: the \: \: mars \: by \:$

$=(6400000 - 4300000)m$

$= 2100000m$

Answer:

=2100000 m
