A circle with a radius of 1/2......................has a circumference of exactly pi...............the unit circle has an area of exactly pi..............the area of a r = 1/2 circle is.........0.785..........area is pi r squared.....1/2 squared is 1/4....................1/4.........like 14i...............1/4 = 0.25.................25 primes under 100..............100 is the first number to have 3 digits..................1st to have 3..............another 13...............



3.14 / 4 = 0.785
