How many miles around is the earth?
I feel the question should be what is the circumference of earth – It is – 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 (or distance around earth) at the equator is 24,902 mi / 40,076 km. so the answer is 24,902 miles or 40,076 kms.
