a flat object. Ex. a peice of paper, the paper is flat not 3d. not 3D.
area is the amount of space on a flat or 3d figure
yes it is however a rectangler prisom is 3d
If its 2d its called a semi-circle, if its 3d its called a semi-sphere.
A spiral is first defined as a flat figure. Sometimes it is used to describe a three dimensional case.

A 3D figure has length x width x depth. It becomes a 2D figure once the removed surface is laid flat, having then only length x width. Another name is "Plane Figure."
A polygon is a flat figure, like a square. A polyhedron is a 3D figure, like a cube.
If its 2d its called a semi-circle, if its 3d its called a semi-sphere.
a polyhedron is any 3d figure with all flat polygons for sides(polygons have straight sides)
3D
A spiral is first defined as a flat figure. Sometimes it is used to describe a three dimensional case.
Sometimes because a sphere which is a 3d figure has a diameter
A 3D figure can be drawn on a flat plane (piece of paper) by using perspective.A horizon (horizontal) line is drawn across the page and a spot marked along the horizon. All side lines of the 3D shape must meet at the spot.Perspective is much used by artists and architects, etc.
