Truncated ninth-angle pyramid
The height of the pyramid is exactly in the center of the nine-cornered base.
Geometric dimensions of the finished pyramid (mm):
Height = 35
this pyramid can be inscribed in a truncated cone with base radii r = 35 mm and R = 55 mm
Geometric dimensions of the finished pyramid (mm):
Height = 50
this pyramid can be inscribed in a truncated cone with base radii r = 25 mm and R = 50 mm
Geometric dimensions of the finished pyramid (mm):
Height = 80
this pyramid can be inscribed in a truncated cone with base radii r = 20 mm and R = 50 mm
