The correct answer is the earth has an equitoral circumference of ~ 24,900 mi and diameter of ~ 7,926mi. With these facts we devise the surface to core distance to be ~3963mi at the equator and 3950mi from the poles.

Earth radius - Wikipedia, the free encyclopedia
Because the Earth is not perfectly spherical, no single value serves as its natural radius. Instead, being nearly spherical, a range of values from 6,357 km to 6,378 km (≈3,950 – 3,963 mi) spans all p...

The distance from the surface of Earth to the center is about 3,963 miles. Much of Earth is fluid. The mostly solid skin of the planet is only 41 miles thick. Relatively speaking, it’s thinner than the skin of an apple.

Because the Earth, like all planets, is not a perfect sphere, the 'radius of Earth' can vary at different places on the surface. The ''radius of the Earth at a point'' on the surface is the distance from the center of the Earth to the mean sea level at that point.

Overall, the approximate distance (radius) from the earth's surface to its center is 6370 kilometers, although the precise distance depends on one's location. The polar radius is smaller than the equatorial radius, implying that the earth's shape deviates from a perfect sphere (it bulges slightly at the equator).
