1841 – 440 were calculated in England.
1946 – 620 digits were correctly ordered.
Right Cylinder– V = πr2h
SA = 2πr2 + 2πrh
Right Cone – V = 1/3 πr2h
SA = πr (l + r)
Sphere– V = 4/3 πr3
SA = 4πr2
It is 165 feet in diameter and has a circumference of 518 feet.
518ft / 165ft ≈ 3.139, which is almost pi.
