The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).
But, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). This the earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

The average radius of the Earth is 3,959 miles (6,374 kilometers).
The equitorial diameter of the Earth (distance from one side of the Earth to the other at the equator) is about 7,926 miles.
The ratio of the circumference to the diameter of a circle (circumference/diameter)
is written as the symbol pi.
Pi is approximately 3.141592.
3.14159265
3.1415926535
Therefore, to determine the circumference from the diameter given above:
equitorial diameter x 3.141592 = equitorial circumference
| |
7,926 x 3.141592 = 24,900

The earth has a circumference of approximately 24,900 miles.
More precisely the circumference of the earth
at the equator is 24,902 mi / 40,076 km.
