A sprinkler on a golf green is set to spray water over a distance of 20 meters and to rotate through an angle of 160°. Find the area of the region that can be irrigated with the sprinkler. (Round your answer to two decimal places.)

I really have no idea how to go about this problem, so I'd appreciate any help anyone could give. Thanks in advance!
