since a rectangle forms two area of a circle shouldn't it also form two circumference in a cylinder

I can make no sense of your question.
the formula for the area of a cylinder is derived by adding the area of a rectangle (circumference of a circle * height of the rectangle forming the circumference) by twice the area of a cycle, since there are two circles in a cylinder. I was asking why it is not 2 circumferences. area=2 pi rh + 2 Pi r^2. why not ...2* 2 pi rh + 2 Pi r^2
