An irrigation system uses a straight sprinkler pipe r = 250 ft long that pivots around a central point as shown. Because of an obstacle the pipe is allowed to pivot through θ = 280° only. Find the area irrigated by this system. (Round your answer to the nearest whole number.)

Area  =   pi * (radius)^2 *  (280/360)  =

 

pi (250) (280/360)  ≈

 

610.87 ft^2  =   

 

611 ft^2
