Solutions due by high noon on Friday, October 23rd.
A cross country and track coach decides that she will make her runners' practice run interesting this week. On a large field, she draws 16 circles, as shown below. She tells the runners that each circle has a radius of 7 meters. She then tells them that they are going to run the path shown by the red/bold parts of the circles.
1. How far will her team run to complete one lap?
2. How many laps will her team need to run to simulate a 5k run (5000 meters)?
3. What is the area bounded inside the path?
