The diagram shows one way to develop the formula for the area of a circle. pieces of a circle with radius r are rearranged to create a shape that resembles a parallelogram.

a circle is shown. the circle is cut into 8 equal pieces. pieces of the circle with radius r are rearranged to create a shape that resembles a parallelogram.

since the circumference of the circle can be represented by 2πr, and the area of a parallelogram is determined using a = bh, which represents the approximate area of the parallelogram-like figure?
