What area will Sam need to cover with black paint on his dartboard? Give the exact answer.
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 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:
