The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers). But, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). This the earth is a tad wider than it...

First or all, let's pretend the Earth is a perfect sphere (it's not, but it puts the math within my realm of understanding.) Now according to my National Geographic map of the world, the earth's equatorial circumference is 24,902 miles. ... Of course, the above is all relative as we are all moving with the earth around the sun,

Imagine a string around the circumference of the earth. Someone makes a proposal to place the string on six-foot-high poles. Obviously this implies that the string will have to be longer. But how much longer? Before trying to figure it out, try a guess: Is it about one thousand miles longer, about a hundred, or about ten?
