NO wonder. Measure of Geometry via Arc-angle [and Pi] is related to TIME. Pi is a point on NUMBER LINE that lies between 3.1415...and 3.1416; which can be equated to 100000/31831, which repeats all by itself at 5244th decimal point.

On my examining the value during 1973-74, I had the value run into Delhi University Campus, Computer Center and published its value to lie between TWO FRACTIONS, and later got this copyrighted as the “POSSIBLE ABSOLUTE VALUE”. Let this be the YET ANOTHER VALUE till I am proved WRONG in my argument advanced during discussions with USMA & Calndr-L members on list (see archives’). Mathematicians may in due course see reason in my pointing to THIS value being *absolute & unique*.

Most scientific calculators have a "pi" key, but if you are forced to use a simple calculator, 355/113 is a good enough approximation for virtually any engineering work (better than 0.1 ppm). Write it as a classic long division problem and you will never forget it. Much less mnemonic, but 104348/33215 agrees with the pi key on my 10 digit calculator. If I subtract them, the calculator gives zero. From: Pat Naughtin <[email protected]> To: U.S. Metric Association <[email protected]> Sent: Sun, May 29, 2011 6:45:54 AM Subject: [USMA:50533] Value of pi On a more serious note, I was brought up in my early education to believe that pi was equal to 22/7 and that all circles had a radius that was a multiple or sub-multiple of 7. These days, if I want a quick value for a circular area I use diameter squared multiplied by 0.8, where 0.8 is an approximation of pi/4 (pi/4 = 0.7854). As an example, my garden rainwater tank is 3 metres in diameter and it is 2 metres up to the overflow pipe. My estimate of its volume, done in my head, goes something like this: 3 metres squared = 9 square metres. 9 square metres times 0.8 = 7.2 square metres = area of the base of the tank (say) 7 square metres. 7 square metres times 2 = 14 cubic metres or 14 000 litres. When I bought this tank it was specified to hold 13 500 litres so it looks like I got a good deal. Cheers, Pat Naughtin Geelong Australia
