Distance to the moon To find the distance to the sun as in Exercise 67, we needed to know the distance to the moon. Here is a way to estimate the distance When the moon is seen at its zenith at a point A on the earth, it is observed to be at the horizon from point B see the following figure. Points A and B are 6155 mi apart, and the radius of the earth is 3960 mi. a Find the angle in degree. b Estimate the distance from point A to the moon.

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.
