The Egyptians used 256 divided with 81 to calculate pi.

In every circle . . .Area = (pi) x (radius)2Diameter = 2 x radiusCircumference = (pi) x diameterIn this circle, Area = (pi) R2 = 81R2 = 81/piR = sqrt( 81/pi )Diameter = 2 x sqrt( 81/pi )Circumference = (pi) x 2 x sqrt( 81/pi ) = 2 x sqrt( 81 pi ) = 18 sqrt(pi) = 31.9042 (rounded)

The radius is 9 feet because pi*92 = 81*pi

pi is not divided into anything - unless you specify pi/2 or pi/3.6

3.14 x 81 = 254.34

Divide the 81 pi by pi, then square root it. (Use the formula for area of circle, which gives 81pi=pi*radius squared, but rearrange to find the radius). i.e. it's the square root of 81
