Volume and Surface Area of Cone

Volume and Surface Area of Cone. Cone is a solid shape with an elliptical base and curved surface that tapers to a point (vertex). Vertex is where : two or more rays or the arms of an angle meet, the adjacent sides of a polygon meet or the edges of a solid figure meet. A cone has a flat base, It has one curved side, Because it has a curved surface it is not a polyhedron.

Surface Area
Surface Area of Base = π × r2, Surface Area of Side = π × r × s
Surface area of Cone = π × r2  + π × r × s

Volume =
