Question

The equatorial diameter of the Earth is approximately 12754 kilometre in length what is the approximate circumference of the earth at the equator?​

Answer 1

The approximate circumference of the earth at the equator is 40084 km

Given, the equitorial diameter of Earth is 12754 km in length.

We know, radius = diameter/2

So, equitorial radius = 12754/2 = 6377 km

For a circle of radius 'r', its circumference is 2Пr.

So, for earth of radius 6377km, its circumference is 2П(6377) km

= 12754П km

= 40084km            [Taking П as = 22/7]

This is the required circumference.

Answer 2

Answer:

The approximate circumference of the earth at the equator is 40084 km

Given, the equitorial diameter of Earth is 12754 km in length.

We know, radius = diameter/2

So, equitorial radius = 12754/2 = 6377 km

For a circle of radius 'r', its circumference is 2Пr.

So, for earth of radius 6377km, its circumference is 2П(6377) km

= 12754П km

= 40084km            [Taking П as = 22/7]

This is the required circumference.
