What are the equations of Circle 1–Circle 5 on the template for Sam’s dartboard?
Sam is sketching a template on graph paper to use as a guide for his painted cork dart board.
The diameter of Circle 1 is 2 feet and the distance between the edges of each of the next three
pairs of circles is 1 foot.The distance between Circle 4 and Circle 5 is 1/2 foot. Sam does not want
axes through or touching his template and therefore wishes to sketch the dart board only in
Quadrant I. At the closest points, he wants Circle 5 to be 1 unit from the y-axis and 1-unit from
the x-axis. In this case:
