The pyramid curve exactly match earth's radius. 2x the perimeter of the bottom of the granite coffer X 10**8 is the sun's mean radius.{ 270.45378502 PI* 10**8 = 427,316 miles}Theres a universal relationship betw the diameter of a circle and its circumference. The ht of the Pyramid's apex is 5,812.98 in, and ea side is 9,131 in fr corner to corner. If the circumference of Pyramid is divided by 2x its ht (the diameter of a circle is 2x the radius), the result is 3.14159, w/c just happens to be…
