I'm thinking center to equator
The average distance from Earth's surface at the equator its center is about 6378 km. The distance from near the north and south poles to the center is somewhat less.
The earth is slightly wider than it is tall, so the measurement around the equator is going to be a just over a hundred miles greater than the distance around the earth.
The distance around the Earth's equator is approximately 4,007,500,000cm.
The closer an object gets to the center of the earth, the greater the pull of gravity on that object.
at the center of the earth
The average distance from Earth's surface at the equator its center is about 6378 km. The distance from near the north and south poles to the center is somewhat less.
The Earth is not a perfect sphere, so the distance to the center of the Earth varies from 6378 km (3963 miles) at the equator to 6357 km (3950 miles) at the poles.
acceleration due to gravity is given by, g=GM/R2 Hence distance from the earth increases g decreases and viceversa. So g at poles is greater than g at equator.
There are two reasons, both related to the Earth's rotation. At the equator, the Earth and the objects on it are at their maximum rotational velocity (about 465 meters per second). This causes the surface of the Earth at the equator to bulge farther from the center of mass, by an average of about 3.5 kilometers.So the effect of gravity is higher at the North Pole than the equator because of:1) the rotational velocity acting to reduce the downward acceleration2) the greater average distance from the Earth's center at the equator, since gravity decreases with distance from the center of mass.The difference, however, is only 0.05%, or 1/200 of the weight.
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.

The equator is the center of the earth's surface which is an equal distance from each pole. The poles are points on both sides of the earth which supposedly create the magnetic field around the earth.
