 Hi and welcome to our session. Let us discuss the following question. The question says, find the volume of the right circular cone with first part is radius 6 centimeters, height 7 centimeters, setting part is radius 3.5 centimeters, height 12 centimeters. Before solving this question, we should know the formula for finding the volume of a cone. Volume of a cone is equal to 1 by 3 pi r square h where r is the base radius and h is the height of the cone. The knowledge of this formula is a key idea in this question. Let us now begin with the solution. The first part we are given radius as 6 centimeters and height as 7 centimeters. We know the value of r and h so we can easily find the volume of a cone and we know that the volume of a cone is equal to 1 by 3 pi r square h. By substituting the values of pi r and h, we get 1 by 3 into 22 by 7 into 6 into 6 into 7 centimeter cube. Now this is equal to cancel 7 from both numerator and denominator. On cancelling 6 by 3 we get 2 and on simplifying this we will get 264 centimeter square. So volume of cone is 264 centimeter square. This completes the first part. In the second part we are given radius as 3.5 centimeters and height as 12 centimeters. We know the value of r and h so we can easily find volume of cone. We know that volume of cone is equal to 1 by 3 pi r square h. By substituting the values of pi r and h we get 1 by 3 into 22 by 7 into 3.5 into 3.5 into 12 centimeter cube. On cancelling 12 by 3 we get 4 and on cancelling 3.5 by 7 we get 0.5 and on further simplifying it we get 22 into 7 centimeter cube and this is equal to 154 centimeter cube. Hence the required answer of the first part is 264 centimeter cube and for the second part there is 154 centimeter cube. So this completes the session. Bye and take care.
