Ex 11.3, 10 A company packages its milk powder in cylindrical container whose base has a diameter of 14 cm and height 20 cm. Company places a label around the surface of the container (as shown in the figure). If the label is placed 2 cm from top and bottom, what is the area of the label. Here, the label is a hollow cylinder, with Diamter = 14 cm Radius = 14/2 = 7 cm and Height = 20 β 2 β 2 = 16 cm Now, Area of label = Curved Surface Area of cylinder = 2ππβ = 2πΓ7Γ16 = 2Γ22/7Γ7Γ16 = 2Γ22Γ16 = 44Γ16 = πππ ππ^π
