Problem

A circle is cut into a large number of thin, congruent sectors. When these sectors are alternately placed head-to-tail, they form a shape that closely resembles a rectangle. If the circle has radius rr, what is the approximate area of this rectangle? (a) 2πr×r2\pi r \times r (b) πr×r\pi r \times r (c) 2r×r2r \times r (d) πr×2r\pi r \times 2r
