Circumference of the Earth The Greek mathematician Eratosthenes ca.276-195 B.C. measured the circumference of the earth from the following observations. He noticed that on a certain day the sun shone directly down a deep well in Syene modern Aswan. At the same time in Alexandria, 500 miles north on the same meridian, the rays of the sun shone at an angle of 7.2 to the zenith. Use this information and the figure to find the radius and circumference of the earth.
