Lecture on Cones and Pyramids

A Cone is a three dimensional solid with a circular base and a curved surface that gradually narrows to a vertex. A 3-dimensional solid in which the base is a circle. A Pyramid is a three dimensional figure with a regular polygon as its base and lateral faces are identical isosceles triangles meeting at a point. Principle objective of this lecture is to present on Cones and Pyramids with example and exercise. A 3-dimensional solid in which the base is a polygon and the sides are triangles which meet in one point called the vertex.
