The length of the equator of the globe will be equal to the length of a circle with a radius of 6400 km.
L = 2 * P * R – the formula for determining the circumference.
L = 2 * 3.14 * 6400 = 40192 km – the length of the equator.
Let’s round the value to thousands:
40192 km = 40 thousand km.
Answer: 40 thousand km
