Some irrigation systems spray water in a circular pattern. You can adjust the nozzle so it sprays in certain directions. The nozzle in the diagram is set so it does not spray the house. If the spray has a radius of 12 ft, what is the approximate length of the arc that the spray creates?
Since we can't see your diagram, you will have to describe the situation in more detail such as , how far is the spray gun from the wall of the house.
