July 22, 2010 : Happy Pi Approximation Day

It’s about that time of year (pun totally intended) – Happy Pi Approximation Day!

An oldie but a goodie.

In case you were wondering,  the approximation of Pi is only 0.04% off of the real thing. It shouldn’t be used for any serious engineering calculations, but it’ll pass for a pretty solid estimate.
