Textbook Question
Chapter 1, Problem 23TS
Examine the nearly similar small and large green “triangles”—the small one with sides a and shadow b, and the larger one with corresponding sides Earth’s radius A and the 800-km distance B between Alexandria and Syene. Note equal ratios a/b = A/B. Knowing that a/b = 1/8, calculate A, the radius of the earth.
