I rest my case

Ok for starters its prime numbers that have the power... 3 and to a lesser extent 4 (base of the pyramids) are the ones most used...

see attached picture with your proposed circle of 18 cm (180mm) and your shape of 30.00mm, 60.00mm, 90.00mm & the computer came back with 94.9mm but thats a small drop...

Now how can i fit "19" of these shapes into that circle? that is how you got 19 right?

I would really like to know how this works and how it could be used for other sized circles???

Now it starts to become intresting.
measuring the volume of 9.49 x3x9 minus 0.49 x3 and then divide by 9 divided by 9

I will try to explain with my poor English.
if you add rectangles side by side formed a circle on the inside of the 3-centimeter sides. ok rectangles do not fit 100% but it takes 19 to make up a circle

in the bible's creation story,(swed. translationI)read the following figures 30,10,5
30 divided by 3 = 10. 15 divided by 3 = 5
