A 3D figure with circles on both ends is called a cylinder. It has two parallel circular bases connected by a curved surface. The distance between the bases is the height of the cylinder, while the radius of the circles defines its width. Common examples include cans and tubes.
One face, the same as a circle. For both a 2D and a 3D oval it's the same. 3D ovals and circles have no vertices or edges. 2D ovals and circles have one edge.
a sphere
Sometimes because a sphere which is a 3d figure has a diameter
A circle is not a 3D figure because it only has two dimensions. A sphere is a 3D "circle".

A cuboid is a 3D shape that can be a cube or a rectangle, both having 2 ends, 2 sides, and a top and a bottom face.

The cone IS a 3d figure.
It depends on the type of figure. If it is a 2D figure, then it is called area. If it is a 3D figure, then it is called volume.
A circle is not a 3D figure because it only has two dimensions. A sphere is a 3D "circle".
A 3D figure shows length, width and depth. While a 2D figure only shows length and width.
Depends
Yes.
A solid.
Both represent a shape and are a 3D figure but, a pyramid only has 1 face and prisms have 2 faces.
