I am curious if the Mathematically inclined members were aware of this !...
I am not sure why but I seem to recall being told that Pi was is from a mathematical constant, the ratio of a circle's circumference to its diameter, ... or it could also be calculated from 22/7 .... which would give approx 3.143 to say 3 decimal places.
But upon checking it on the internet , I find this is not the case.
It shows Pi as being 3.14159 to 5 decimal places.

Am I the only one to have thought this I wonder ?

That's the definition of Pi, the circumference of a circle divided by its diameter.

No, the first times I heard about Pi it was presented to me as 3.1416.
Thanks for your Confirmation ArMaP.
Out of curiosity ...Was it ever later presented or was you ever aware of it being suggested to you as 22/7 ?

What values do you use to get that result?
22/7 is an approximation of Pi but it is not exact. 3.14159 but it is an irrational number and can not be represented decimally exactly. An irrational number goes on forever after the decimal point.
I had not been aware "Z" that the Egyptians had used Pi in relation with the Pyramid...Maybe its on the links I posted but I did not take note as yet :-\
I think I always thought of Pi being associated with Circles..rather than triangles or squares..although I have seen geometry with triangles and squares both within and outside circles..Maybe this is how they related to it...

Thanks for confirming Pimander , that I was not the only one who had related to Pi maybe as 22/7 even if just as an approximation.
Coincidentally its also the first two letters in your name.. :)

Sacred Geometry "Squaring of the Circle" It's an Illuminati thing :P
The Golden Ratio & Squaring the Circle in the Great PyramidDartmouth University Math Program Sacred Geometry"Twenty years were spent in erecting the pyramid itself: of this, which is square, each face is eight plethra, and the height is the same; it is composed of polished stones, and jointed with the greatest exactness; none of the stones are less than thirty feet." -Heroditus, Chap. II, para. 124.

Slide 2-1: The Giza Pyramids and Sphinx as depicted in 1610, showing European travelers Tompkins, Peter. Secrets of the Great Pyramid. NY: Harper, 1971. p. 22
Now we'll look at his other claim, that the Great Pyramid's dimensions also show squaring of the circle. But just what is that?
The problem of squaring the circle is one of constructing, using only compass and straightedge;
(a) a square whose perimeter is exactly equal to the perimeter of a given circle, or
(b) a square whose area is exactly equal to the area of a given circle.
There were many attempts to square the circle over the centuries, and many approximate solutions, some of which we'll cover. However it was proved in the nineteenth century that an exact solution was impossible.
See the math on the site (it won't paste here) The result?

PI AND THE GREAT PYRAMIDQuoteThese considerations suggest that the famous relationship between &pi and the Great Pyramid of Khufu is a coincidence which has its roots in two facts - one purely mathematical and the other historical, but both involving the number 7:
1. The rational number 22/7 happens to be an excellent approximation to the number pi.
2. The Egyptian measurement system involves dividing one unit of measurement(the cubit) into 7 equal units (palms)
Concerning the first fact, it is actually somewhat remarkable that an irrational number such as &pi can be approximated so well by a rational number with a small denominator. (The denominator is 7 in this case.) Concerning the second fact, the reason why Egyptians chose to divide a cubit into 7 parts might be quite hard to trace. It would seem to go back long before the construction of the Great Pyramid, at least to the time of Imhotep.

Thanks to that link I now understand where you got your (wrong) "PI = Perimeter of base of the Great Pyramid divided by it's height". :)
This relates to 2 X Pi being Perimeter of Base / Height.
if so....
Is Pi then = to Perimeter of base / height X 2

Yes .. Stonehenge does look like it was a series of PI's in a circle when it was in its original form.

Here is one 'mainstreamer' that says we need to look at ALL the pyramids to base our conclusions on :P not just the main one.
But then the main one is the important one All the rest are later copies :D
I include him ONLY because of the 22/7 reference
Khufu's Pyramid does not "contain" Pi...
Numerous authors have made small fortunes out of "discovering" that the transcendental number pi is hidden in the Great Pyramid. This idea has arisen because of the observation that the ratio of opposite : adjacent, often used to determine slope angle, is 14 : 11. If the height of the Great Pyramid is 14 units, then half of one side is 11 units, then the periphery at the base must be 8 x 11 = 88. If you are into playing with figures, you might notice that 88 / 14 is the same as 2 x 22 / 7 and, as every schoolchild knows, 22 / 7 is a 20th century approximation for pi.
http://egypt.hitchins.net/the-pyramids/pyramid-myths/khufus-pyramid-does-not.html
How does he know they didn't approximate back in the days of the Greek Scholars too? :P
It also assumes that the great Pyramid was built by Khufu :P

In fact you only need a rope. A rope can be a straight line or be tied to something and used as a compass.

The sacred cord was a knotted rope held by a "priest". The rope and knots could be used to create the angles and lay the ground plan for permanent and temporary "temples".... Archaeologists think every building they do not understand is a temple. :)
So geometry (remember I told you that the real masonic secrets were really geometric) is likely to have originated with the measurement of time (the seasons) and the invention of rope.
To measure the seasons all you need to do is hammer a post (or more permanently a very heavy stone ;) ) and mark where the shadows are at sunset and sunrise with more posts (or stones ;) ). The posts at the extremes mark the Summer Solstice and Winter Solstices, Spring and Summer Equinox. COmbine this information with the geometric measurements possibly using a sacred cord (rope) and you have early temple building.
The ultimate expressions of this knowledge can be seen in Egypt and the Gothic Cathedrals in Europe. Most modern architecture pales in comparison.
Next we come to the knotted rope/cord and its symbolic association with the spinal cord (oooh, another coincidence word ;) ) and some (ooooh) say the chakras! Then there is rope and DNA. But that is enough "secrets" for now.... Hahahaha...
