The radius of the earth is 6,380 kilometers. What is the radius of the earth in centimeters?

Solution:

We know that

1km = 1000m and 1m = 100cm

So 1 km = 1,00,000 cm

It is given that

Radius of the earth = 6,380 kilometers

We have to find the radius of the earth in centimeters

Let us take it as:

Radius of the earth = 6,380 × 1,00,000

So we get,

Radius of the earth = 638 × 10⁶ cm

Therefore, the radius of the earth in centimeters is 638 × 10⁶ cm.

The radius of the earth is 6,380 kilometers. What is the radius of the earth in centimeters?

Summary:

If the radius of the earth is 6,380 kilometers then the radius of the earth in centimeters is 638 × 10⁶ cm.
