- The definition of a paraboloid is a solid with two or more parabolic sections parallel to a single axis, or is a solid generated by rotating a parabola around a center point (axis).
A solid made by rotating a parabola around an axis is an example of a paraboloid.
a surface or solid formed so that sections parallel to the plane of symmetry are parabolas and sections perpendicular to it are ellipses (), hyperbolas (), or circles ()
A surface having parabolic sections parallel to a single coordinate axis and elliptic or circular sections perpendicular to that axis.
