At the equator, an average of 12756km. The equator is, however, slightly elliptical, and the poles are maybe 40km more flattened. This is actually a mathematical problem, not a scientific one. A kilometre was originally defined as 1/10000 of the distance between the North Pole and the Equator on a line passing through Calais. Earth's circumference, assuming it to be a perfect sphere, would therefore be a 40000km circle and its diameter would therefore be 40000/pi km, which is 12732km. This is wrong because Earth isn't a perfect sphere and the definition of the kilometre has changed.

The diameter of the moon is about one quarter of the diameter of the Earth

Earth ranks fifth in size among the nine planets. It has a diameter of about 8,000 miles (13,000 kilometers). Jupiter, the largest planet, is about 11 times larger in diameter than Earth. Pluto, the smallest planet, has a diameter less than one-fifth that of Earth.

the diameter of the earth is c/pi=d so circumference (25000 miles) divided by pi (3.14) = diameter
so the diameter is ~ 7961.783miles

Did you confuse Genealogy with Geology?
