 Hi and welcome to the session. Let us discuss the following question. The question says, a company packages its milk powder in cylindrical containers whose base has a diameter of 14 centimeter and height 20 centimeter. Company places a label around the surface of the container as shown in the figure. If the label is placed 2 centimeter from the top and bottom, what is the area of the label? So here we have a cylindrical container whose diameter of the base is 14 centimeters, height is 20 centimeters and the label is placed 2 centimeter from the top and the bottom. Now before proceeding for the solution, let's recall the formula of lateral surface area of a cylinder and that is equal to 2 pi r h where r is the radius of the base of the cylinder and h is the height of the cylinder. This is the key idea for this question. Let's proceed with its solution now. Given in the question that the diameter of the base of the cylindrical container is 14 centimeters. So this implies radius r is equal to 14 upon 2 centimeters that is equal to 7 centimeters. Also the height of the cylinder is equal to 20 centimeters. Now we need to find the area of the label. So we will find the height of the label. The label is 2 centimeters less from the top and 2 centimeters less from the bottom. So we will subtract 2 plus 2 centimeters from the total height of the cylinder that is 20 centimeters. So we will get the height of the label equal to 20 minus 2 plus 2 centimeters that is equal to 20 minus 4 that is 16 centimeters. Let us name it as capital H. So let us find out the lateral surface area of the label. And this will be equal to 2 pi r into height of the label that is capital H. Substituting the values we get into pi that is 22 by 7 into r r that is radius is equal to 7 centimeters into h. h is 16 centimeters. So here 7 and 7 will get cancelled and we will get 44 into 16 centimeters square that is 704 centimeters square. So the required area of the label is 704 centimeters square. With this we finish this session. Hope you must have understood the question. Goodbye take care and have a nice day.
