Hint:
Earth is not completely spherical in nature. It is elliptical in nature. The radius along the equator is more than the radius along the poles.

The earth processes two radiuses along the two axes that is the north-south axis and the east west axis. The radius of the earth along its equatorial Axis that is the east-west axis is $6378.1$ kilometre and the polar eight years or we can say the radius around the polar axis is $6356.8$ kilometre. The polar access is also known as the North South axis. Twice of the radius will give us the value of diameter hence the diameter along the equatorial Axis east-west axis will be $6378.1 \times 2 = 12756.2$.
