The PERIMETER of the equator cycle is about 40,000Km. The Greenwich cycle is a bit shorter as the earth is a bit an ellipsoid. About 37,000Km by Google Maps. The distance on the envelope between ANY antipodes (=opposite points on the axis, I won't use "diameter" to avoid confusion) is HALF the perimeter (If you walk the whole perimeter long, you'd get to the same point, of course). The distance through Earth is
D=P/Pi=37,000Km/Pi=about11777Km
Andorra because all the rest end in -ia
The basic clarification for these covered diverts in the Mississippi River delta in south Louisiana is that they speak to channels of the Mississippi stream delta when ocean level was lower, amid the ice age.
I hope the answer will help you.
