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.
The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km)

Approximately 1800 miles to the outermost boundary of the core. Then nearly another 2200 miles to its centre.
