You may want to look at these sites:
Then the following is found on the second site I have listed:
" few more numbers for you...the circumference of the Earth is 24,901.55 miles (40,075.16 km) at the equator. If you were to measure from the north pole to the south pole and back to the north pole, the circumference would be a bit shorter. That is because the Earth bulges a little bit around its waist (the
equator). This "equatorial bulge" is caused by the Earth's spin - try spinning a water balloon as you toss it up into the air to see how this works. Tidal forces caused by the pull of gravity from the Sun and Moon also add a little to this bulge. So the pole to pole circumference is 24,859.82 miles (40,008 km)."
Hope this helps
