The answer depends on where a plane cuts through the cylinder. It could be a circle, ellipse, rectangle or square.
Not sure what the projection on a plane at an angle to the length of the cylinder would be. A parabola?
Plus there are other section where the
the cylinder has 2 2d shapes: the 2 circles on the end
A cylinder is not a 2D object because it has three dimensions - length, width, and height. It has a circular base and a curved surface, which give it depth. A 2D object would only have two dimensions and would lack any depth or thickness.

A cylinder is a three-dimensional geometric shape, not a two-dimensional one. However, if we refer to its 2D representation, it can be visualized as a rectangle (representing the curved surface when unwrapped) and two circles (representing the top and bottom bases). In 2D, the essential characteristics of a cylinder are depicted through these shapes, highlighting its circular bases and height.
The 2D parallel shape that represents a cross section of a cylinder is a circle. When a cylinder is sliced parallel to its base, each cross section reveals a circular shape, regardless of where the cut is made along the height of the cylinder. This circular cross section maintains the same diameter as the bases of the cylinder.
You cannot have a 2d cylinder. The 2d cross section will depend on the plane of the cross section.

There is no such thing.

no, it's a 3D shape. (:

circle, oval
The awnswer before was wrong. I was looking for the2D shape of a cylinder.
1 rectangle and 2 circle.
A rectangle (rolled into a circular shape).
