  1. Radius of Main circle is 9 and radius of unit circle is 1. Without using any algebra, with scissors or folding we can find the areas of main circle in terms of unit circle. Now, imagine the little square there Surrounded the circle well. The areas in the square that re not in The circle are directly proportional to The size of the circle. So that if the area outside of the little Circle was x, the area of a circle with Four times that area would be 4x. That also means that the area of these Square is DIRECTLY proportional to The area the circle. This means, that if you want to know The area of the circle. All you have to Do is find out how many of the little Squares there are in the big square. YOU CANNOT ANS. THIS BY FOLD- ING THE LARGE CIRCLE.
