Last updated about 5 years ago

Martin the Martian lives on Planet Mart. Martin wants to know the circumference of Planet Mart, but it is too large to measure directly. He uses the same method as Erastothenes by measuring the angle of the sun’s rays in two locations. The sun shines on a flagpole in Martinsburg, but there is no shadow. At the same time, the sun shines on a flagpole in Martville, and a shadow forms a 10 degree angle with the pole. The distance from Martville to Martinsburg is 294 miles. What is the circumference of Planet Mart?
