This volume depends on the radius of the sphere (i.e, the distance of any point on the surface of the sphere from its center). If we take the cross-section of the sphere then the radius can be calculated by reducing the length of the diameter to its half.

WebbThe volume of the pyramids is: 8 ⋅ 1 3r2 ⋅ r = 8 3r3, and then we can calculate that the bicylinder volume is (2r)3 − 8 3r3 = 16 3 r3.
