(plz asap) 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. 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?

If u cant see it here's the answer, the first numbers are in a fraction 1/2 (2πr)(r) so its C

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
