Depends on where you take your cross-section. If you look at it from the top, it's a circle. If you look at it from the side, it's a rectangle. And that's only if you don't approach it from something other than a right angle.
If it is folded out it is called a net. It forms two circles and a rectangle.
There is no such thing.
A quadrilateral rectangle or a square
A cylinder has three 2D faces: two circular faces at the top and bottom, and one rectangular face that wraps around the side. The circular faces are the bases, while the rectangular face represents the curved surface when unrolled.
A 2D shape with forty sides is known as a tentracontagon.
You cannot have a 2d cylinder. The 2d cross section will depend on the plane of the cross section.
the cylinder has 2 2d shapes: the 2 circles on the end
If it is folded out it is called a net. It forms two circles and a rectangle.
There is no such thing.
Well it depends if you look at it from the top it is a circle if you look at it from the side it is a rectangle.
You cannot have a 2d cylinder. The 2d cross section will depend on the plane of the cross section.
a circle is a 2D shape while a cylinder is 3D shape
no, it's a 3D shape. (:
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.
A 2D sphere is a circle.
A 2d nine sided shape is called a nonagon.
