2. The Power Point consists of: What is a cone? Formulas of Cone:- Total Surface Area Lateral Surface Area Volume Cones used in daily life.

3. CONE A cone is a solid that has a circular base and a single vertex. If the vertex is over the center of the base, it is called a right cone. If it is not, it is called an oblique cone. An object that is shaped like a cone is said to be 'conical'. More precisely, it is the solid figure bounded by a base in a plane and by a surface (called the lateral surface). fferent Shaped Cones

4. FORMULAS OF CONE r=Radius of base of cone h=Height of cone l=Length of cone If length not given:- Length= h 2 +r 2 (Pythagoras Theorem= c 2 = a 2 +b 2 )

5. CURVED SURFACE AREA OF CONE Curved Surface Area of Cone(CSA)= rl                                 

6. TOTAL SURFACE AREA OF CONE Total Surface Area of Cone(TSA) =base area+CSA = r 2 + rl = r( l+r )

7. VOLUME OF CONE

8. VOLUME OF A CONE VS CYLINDER The volume formulas for cones and cylinders are :  The volume of a cylinder is: π  × r 2  × h The volume of a cone is: π  × r 2  × (h/3) So, the only difference is that a cone's volume is one third ( 1 / 3 ) of a cylinder's. So, in future, order your ice creams in cylinders, not cones, you get 3 times more!
