The area of a square........is its side squared...................the r = 1/2 circle..............is completely contained in the square......whose side is one...................unit circle.......one square......symetery.................so..........to find the area........of the 4 wedges............or parts between the 1/2 circle...........and the 1 square at center.........just subtract the two areas......................i use.......0.78..................b/c it matches ......1/2.........the critical line..........13............the 1st 3 digits...........the one square has an area of 1............b/c one squared is one.........................kinda like 11.............................................so.......1 - 0.78 = 0.22.....................two twos.............two 2's............so familiar.................2 + 2 = 4..............2 * 2 = 4............................2 times the square root of 2 is the same as the square root of 8.....................and begins.....2.828..............two 28s in e................the 1st ten numbers of e...............man what symmetry.............



3.14 / 4 = 0.785
