1. Play with the sliders a bit. What does each slider do?[br][br]Suppose the circle has radius r.[br]If we put each slider at its right end (n=80, i=2), the shape we get is nearly, but not quite, a parallelogram. You might even call it a near-rectangle, but I'll call it a "parallelogram". By moving i between 0 and 2, answer these questions:[br][br]2. What is the height of the "parallelogram"?[br][br]3. What is the width of the "parallelogram"?[br][br]Now for the punch line:[br][br]4. What is the area of the "parallelogram"?[br][br]5. What is the area of the circle?
