For use with pages 671–679 Satellite Television Satellite television companies use stationary satellites to transmit programming to their customers. They need the stable coverage to ensure customer satisfaction. The companies must maximize the area covered by each satellite in their network. They want to launch as few satellites as possible to completely cover an area. To do this, they must find out how much of Earth is covered by one satellite. In Exercises 1–6, use the following information. The satellite at points is a stationary satellite in the network of a satellite television company. It is hovering A 400 miles above Earth. The radius of Earth is approximately 4000 miles. Name the central angle that intercepts the arc covered by the satellite. What is the length of ?
