auditory (pharyngotympanic) tube
Strictly, if it has a circular base, it is a circular cylinder. Otherwise, it could have an oval base. If the long axis is at right angles (perpendicular) to the plane of the base, then it is a right circular cylinder.
A point.
If it is a right circular cone, it has an infinite number of planes of symmetry. If it is an oblique circular cone, it has one plane of symmetry.
The "conic section" that is produced when a right circular cone intersects a plane that runs parallel to the edge of the cone is a parabola. In the case where the plane also intersects the vertex of the cone, the parabola becomes two intersecting lines.
A Parabola.
The three circular passages you may be referring to are the three coordinate planes in three-dimensional space: the xy-plane, the yz-plane, and the xz-plane. Each plane is perpendicular to the other two and contains a circular path.
The name 'manifold' is used to describe such a construct. Assuming that the three circular spaces are indeed connected. The three planes need not be orthogonal - that is at right angles to each other.
No, only one UNIQUE Plane.

Yes
A plane circular shape.
A shape with a circular base and a vertex that isn't in the same plane as the base is called a cone.
A circular plane surface
Conic Sections are figures that can be formed by slicing a three dimensional right circular cone with a plane. There are different ways to do this, and each way yields a different figure. These figures can be represented on the graph as well as algebraically. The four conic sections are circles, ellipses, parabolas, and hyperbolas.
A sphere intersected by a plane, An circular ellipsoid intersected by a plane, A cylinder, A cone, and many more shapes, some of which don't even have a name!
A parabola is the figure formed by the intersection of a circular cone and a plane that lies parallel to the edge of the cone. (the cone does not have to be a right [90°] circular cone).
The line or plane upon which a geometric figure is thought of as resting is called the base. A three-dimensional figure with a circular base and the top meeting at a vertex; it resembles a funnel cone.
