What is the radius of the earth?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The average radius of the Earth is approximately 6,371 kilometers (3,959 miles). It's important to note that the Earth is not a perfect sphere but rather an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator due to its rotation. The equatorial radius (distance from the center to the equator) is slightly larger than the polar radius (distance from the center to the poles) due to this flattening effect. The values given represent the average radius, providing a useful measure for general calculations.
