WebEquatorial radius of the earth: A dynamical determination An interesting variation on the familiar method of determining the earth's equatorial radius a sub e, from a knowledge of the earth's equatorial gravity is suggested. The value of equatorial radius thus found is 6378,142 + or - 5 meters. WebOn solving the circumference of the earth we get 39,350 kilometres. So the radius of the earth will be. Circumference = 2πr. 39,350 = 2 × 3.14 × r. r = 39350/ 6.28 = 6267 kilometer.
