Eratosthenes measurement of the size of our planet over 2000 years ago, but we will do it on a hypothetical planet. At one location on that planet at noon, the light from its star comes in directly overhead. At another town 200 miles due South, the shadows cast by the towers in that town indicate that the sunlight is coming in at an angle of approximately 10 degrees from directly overhead. Using this information (and the fact that there are 360 degrees in a circle and that the diameter of a circle is equal to the circumstances divided by pi), please show your work to explain what the circumstances and diameter of this new planet is
