Because it has a volume so therefore it is a 3d object whereas 2d shapes are normally flat and have no volume.
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.
the cylinder has 2 2d shapes: the 2 circles on the end
Well, a 2D object has only length and width, but a 3D object has length, width, and depth.
a circle is a 2D shape while a cylinder is 3D shape
The cross section, of a 3D object, is the 2D shape made when a 2D plane cuts across the 3D object. Often "cross section" refers to the shape made when the plane is at right angles to an axis of the 3D object but this need not be the case.
a pyramid is a 3D objecta triangle is a 2D object
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
There is no such thing.
2d is 2 dimensional, or a flat object.
Well, a 2D object has only length and width, but a 3D object has length, width, and depth.
a 2D object is is flat and on the other hand a 3D object is bulgy
You cannot have a 2d cylinder. The 2d cross section will depend on the plane of the cross section.
yaa, you need to master how the formation of a 2D object, then it is very easy to form a 2D object into 3D shapes
no, it's a 3D shape. (:
a circle is a 2D shape while a cylinder is 3D shape
the answer is , in simple words 2D and 3D , a cylinder is a circle a having an extruded part. while a circle is only a 2D having no extrusion.
Pentagon 2d shape is a pentagon 3d object is a pyramid.
