The length of the Earth’s equator is equal to the length of a circle with a radius equal to the radius of the globe.
L = 2 * Pi * R, which is numerically at R = 6371 km is equal to:
2 * 3.14 * 6371 km = 6.28 * 6371 km = 40009.88 km.
Thus, the length of the Earth’s equator is 40009.88 km.
Answer: 40009.88.
