PLEASE HELP> During the summer time you decide to set up a sprinkler to keep you cool. Assuming with full water pressure the sprinkler can spray everything within a four-foot radius. The sprinkler has been set up to only hit the sector where you are sitting. If it is set to spray a sector area of 9.75 square meters, to what angle is the sprinkler set? Round to the nearest hundredths of a degree.
