Cylinder FAQs:


Q: Is cylinder understood to refer to a finite section of a right circular cylinder having a finite height with circular ends perpendicular to the axis as shown in the figure?

A: Yes.

Q: Is cylinder defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines?

A: Yes.

Q: Is cylinder a degenerate quadric because at least one of the coordinates does not appear in the equation?

A: Yes.
