no it's not. 22/7 = 3 r 1. 10/7 = 1 r 3. 30/7 = 4 r 2. 20/7 2 r 6. at this point we're at 3.146. it's CLOSE but it's not the calculation. "pi - in mathematics, the symbol ϖ denoting the ratio of the circumference of a circle to its diameter. The ratio is approximately 3.14159265, pi being an irrational number (one that cannot be expressed as a simple fraction or as a decimal with a finite number of decimal places) and a transcendental number (one without continuously recurrent digits)." encylopedia britannica online, http://members.eb.com/bol/topic?eu=61387&sctn=1#s_top
