A cylinder is best described as congruent on parallel planes or discs.
The solid enclosed by this surface and by two planes perpendicular to the axis is also called a cylinder.
A cylinder
There are many possible answers: A cylinder A cone sliced by two planes perperndicular to its axis A toroid (doughnut) sliced by a plane vertical to its axis. A sphere sliced by two planes An ellipsoid sliced by two planes A paraboloid sliced by two planes etc.
Two.
There are infinite planes of symmetry in a cylinder in the same way that a circle has infinite lines of symmetry.
two of the faces of a cylinder are circles circles have an infinite number of lines of symmetry therefore cylinders have an infinite number of planes of symmetry

A cylinder
Many solids. Some are: A sphere intersected by two planes, An ellipsoid intersected by two planes, Any blob intersected by two planes, A toroid (doughnut) with a wedge removed, A double-cone intersected by two planes, A cylinder.

Oh, dude, a cylinder has infinitely many lines of symmetry. Yeah, that's right, infinitely! So, like, you can keep turning it and it'll look the same from all angles. It's like the gift that keeps on giving... symmetry!
There are many possible answers. Some are: A sphere or ellipsoid intersected by two planes; A toroid (doughnut) with a wedge cut out; A cylinder; A frustum of a cone.
The given description fits that of a cylinder
