Q. What is Pi. (This does NOT state it can`t be approximate)

22/7

3.1415926

355/113

Circumference of a circle+diameter (Best answer)

PHI^2*6/5 (Geometry)

[ Where PHI = (sqrt(5)+1)/2)….PHI^2=PHI+1… Accurate to 4 decimal places! ]

This (geometric) value was incorperated to draw angles in 9 degree increments using only straight edge and compass! Accuracy only limited to the precision of the compass used!

I find it odd, these values are not found in modern Trig, Books!

See PHI/2 & such in Trig.Book!

These answers should all be considered accepted values
