A cone is a geometrical figure with one curved surface and one circular surface at the bottom. The top of the curved surface is called the apex of the cone. An edge that joins the curved surface with the circular surface is called the curved edge of the cone.Know More
If the apex of the cone lies just above the center of the circular base, it is called a right circular cone. Oblique cones do not have the apex directly above the center of the base. The curved height or slant height of the cone is called the lateral height of the cone.
The cone may be hollow or solid. The curved surface area of the cone is calculated by the formula A=?rs where r is the radius of the base, and s is the slant height of the cone. The total surface area of the cone is given by A=?r(r+s).Learn more about Shapes
The volume of a cone is found by multiplying the area of the circular base by the height of the cone, and then dividing the product by 3. The area of the base is found by taking the square of the radius and multiplying it by pi.Full Answer >
A cone has one edge. The edge appears at the intersection of of the circular plane surface with the curved surface originating from the cone's vertex.Full Answer >
A cone does not have a vertex. A vertex is defined as a point where two lines meet; a triangle has three vertices, and the angular face of a pyramid has a vertex. However, a cone is a three-dimensional figure and has a curved surface.Full Answer >
A cone has one face. It is a three-dimensional shape with a circular base, one side and one vertex. Faces can be identified as the flat surfaces on a three-dimensional figure.Full Answer >
