Answer:

A solid hollow cylinder has an "infinite number of planes of symmetry".

Step-by-step explanation:

  • Two or more faces are said to be symmetric when they have the same dimensions and are geometrically identical.
  • When these faces are placed in a setting with 'X', 'Y' and 'Z' axes "perpendicular to each other", they make a plane with three lines of symmetry. A circle has "infinite lines of symmetry".
  • Thus, a cylinder with two openings has an "infinite number" of "planes of symmetry".
