Math Problem Statement
An irrigation system uses a straight sprinkler pipe r = 400 ft long that pivots around a central point as shown. Because of an obstacle the pipe is allowed to pivot through 𝜃 = 220° only. Find the area irrigated by this system. (Round your answer to the nearest whole number.)
