4. An experiment is conducted to determine the circumference of the Earth. Two poles of equal height ( 3 meters) are placed perpendicular to a tangent line on the Earth's surface as shown. The pole nearer the equator is 800Km from the more northern pole. The length of the shadow cast by each pole is measured at exactly the same time. No other measurement can be taken. Devise a procedure for processing this data to determine the circumference of the Earth. Assume the shadows are small enough toapproximate the ground beneath them as flat.
