HA : AS = (circle in cyl.) : (circle in sph. + circle in cone)
as
HA . (circle in sph. + circle in cone) = AS . (circle in cyl.)]
Therefore
The circle in the cylinder, placed where it is, is in equilibrium, about A, with the circle in the sphere together with the circle in the cone, if both the latter circles are placed with their centers of gravity at H.
