**Find Surface Area and Volume of Cone and Sphere**

Prime purpose of this lecture is to present on Surface Area and Volume of Cone and Sphere. Cone is a surface generated by a straight line that moves along a closed curve while always passing through a fixed point. Sphere is a Surface of which every point is the same distance from a fixed point known as the centre. From every aspect it has the same appearance. A sphere may be described by the rotation of a semicircle or circle, about its diameter.
