It is an edge.
If its 2d its called a semi-circle, if its 3d its called a semi-sphere.
Surface area is all the areas for a 3 figure. Area is for only on side of a 3d figure
Where two faces meet on a 3D figure is called an edge. An edge is the line segment that connects two vertices, which are the points where the faces intersect. In polyhedra, edges play a crucial role in defining the shape and structure of the figure. Each edge is shared between two adjoining faces, contributing to the overall geometry of the solid.
An edge is an area of a 3D figure where two faces meet to form a line segment.
A 2D seven sided figure is called a heptagon. A 3D seven faced polygon is called a heptahedron.
If its 2d its called a semi-circle, if its 3d its called a semi-sphere.
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 solid.
Yes.
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.
A line (2D), ray (2D), vector (2D), line segment (2D), a mobius strip (3D), or a klein bottle (3D).
Volume if it's a 3D figure and area if it's a 2D figure

A three-dimensional figure with 30 faces is called a triacontahedron.
