Question 972846: The water sprays 30 yards from the head of each sprinkler in a semicircular pattern. One of the sprinklers is broken and instead of rotating 180 degrees to water its portion of the field, it is only able to rotate 72 degrees.

The area of the entire circle with radius 30 yards is 900 pi sq yds. (9pi r^2; r=30)
72 degrees of this is (1/5) of the entire circle's area or 180 pi=565.5 yds^2
