Area of true earth is about .515 billion square kms, ie 4 pi r squared = 4 x 22/7 x 6400 x 6400 (r is radius at equator)

Flat earth model would be about 1.257 billion square kms, ie pi r squared = 22/7 x 20000 x 20000 (r is radius from north pole to ice wall, or the same as half the circumference of the world which is 40000 kms)

So lucky us, the earth is almost 2.5 times as big as we thought so there must be plenty of hidden resources for NASA to plunder. However, based on the FE model, the Southern Hemisphere has 4 times the area of the northern hemisphere, so I think it is about time the southern hemispherers decide that we should rule the world.

Note however, that the circumference at the equator is about 40000 kms, would then using basic maths make the distance from the equator to the north pole suddenly shrink to 6400 on the flat earth map, or alternatively, if the distance from the north pole to the equator was 10000 km, the circumference at the equator would be 63000 kms. (using circle circumference = 2 pi r ). So here is the dilemma FE'ers, what is the equatorial circumference and how far is it from the equator to the north pole? Perhaps this has been answered before, but the search always seems broken for me so I cannot find it)
