1.26 W L 8.1.2 Exam: Semester 2 . The circumference of a circle is given by the formula C = 2, where ris the radius. . If the circle is divided into equally sized sectors, the sectors can be rearranged to form a shape that approximates a parallelogram. . The base of the parallelogram is half the circumference, or s , and the height of the parallelogram is r. . Because the area of a parallelogram is equal to the of the base and the height, the area is the of nir and r, or MR. . Therefore, the area of a circle is given by the formula
