[The Great Pyramid of Jeezeh]
The Great Pyramid of Jeezeh
A C Height of Pyramid.
D B Diameter of Pyramid— 365*242 Pyramid Cubits.
E F G H Base of Pyramid.
A B C D Diametrical Vertical Section.
A EC J Diagonal Vertical Section.
AC is to twice DB as π, or as 1 is to 3.14159, or as the diameter is to the circumference of a circle.
And A D B, the right section of the Pyramid, is to EFGH, the area of the base, as π, or as 1 is to 3.14159, or as the diameter to the circumference of a circle.
And AC, the height, is the radius of a circle equal in circumference to the external lines of the square base.
Thus actually squaring the circle as accurately as possible.
