WebIf the earth is a globe, and is 25,000 English statute miles in circumference, the surface of all standing water must have a certain degree of convexity—every part must be an arc of a circle. From the summit of any such arc there will exist a curvature or declination of 8 inches in the first statute mile. WebFrom the equivalence of alternate interior angles across a line transverse to two parallel lines, \angle A = \angle B = 1/50 ∠A= ∠B = 1/50 of a circle. Since angle B is 1/50 1/50 th of a circle and sweeps an arc at the earth’s surface of 5,000 stades, the Earth’s circumference would be 5,000\times 50 = 250,000 5,000×50 = 250,000 stades.
