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.

Given: Diameter of cylindrical container = 14 cm

∴ Radius of cylindrical container, r = 7 cm

Height of cylindrical container = 20 cm

Height of the label, h = 20 – 2 – 2

= 16 cm

Curved surface area of label = 2 π r h

= 2 × (22/7) × 7 × 16

= 704 cm^{2}

Hence the area of the label of 704 cm^{2}.
