Future Snake Eater,
You have misinterpreted my response. There is no area measurement in what I stated. Instead, it is a statement of trigonometry. To wit:
If the earth were a 25,000 mile circumference globe, then, using the Pythagorean Theory (in the first few miles):
In the first (1) mile there would be 8 inches of curve.
1 x 1 x 8 = 8 inches
In the second (2) mile there would be a combined 32 inches of curve.
2 x 2 x 8 = 32 inches
In the third (3) mile there would be a combined 32 inches of curve.
3 x 3 x 8 = 72 inches
Note that stating “squared” is merely a shorthand way of saying that the number is multiplied by itself; (1 x 1), (2 x 2), (3 x 3), etc.
1 mile x 1 mile x 8 inches = 8 inches
Is that what you’re saying?
72 inches of curve
