Ahmes left clues to the Egyptian method for estimating pi = 22/7 ... in

http://planetmath.org/encyclopedia/RMP35To38PlusRMP66.html

and other problems.

1. build a square/cubic container 10 cubit x 10 cubit x 10 cubit ... fill it, and drain the contents into a larger round cylinder ...measure the height filled .. estimate pi by the well known formula

2. find a smaller round cylinder, fill it, and drain contents into a 10 cubit x 10 cubit x 10 cubit container ... and measure its height ... estimate pi

3. compare pi in steps 1 and steps 2, and average close to 22/7 as RMP 38 discusses 1/320 errors, and not near 256/81.
