 Hi and how are you all today? My name is Priyanka and the question says if the little surface area of a cylinder is 94.2 centimeter cube and its height is 5 centimeter then find the radius of its space and then its volume. We are also given that we need to use the value of pi as 3.14. Before proceeding on with the solution we should be well versed with the formula of lateral surface area of a cylinder and that is equal to is 2 pi r h that is the lateral surface of the curved surface area of a cylinder. So the knowledge of this formula is the key idea to this question. Now we are given that the lateral surface area is equal to 2 pi r h. The lateral surface area is given to us as 94.2 centimeter square. Right? So this implies 94.2 centimeter square is equal to 2 pi we do not know the value of r and the h is 5 centimeters. So this implies 94.2 into 7 the whole divided by 2 into 22 into 5 is equal to r after simplifying we have 3 centimeter as the radius of base. So this is the answer to the first part. Now we need to find out for the second part that is its volume that will be pi r square h 22 by 7 r square means 3 times 2 times 3 into h h is 5. So the answer comes out to be 141.3 centimeter cube. So for the first part the answer was 3 centimeter and for the second part it was 141.3 centimeter cube. So hope you understood it well and enjoyed it. Have a good day.
