Diameter of the container = 14 cm

Radius = 7 cm

Height of the container = 20 cm

Curved surface area of the container = 2πrh

= 2 x 22/7 x 7 x 20

= 880 cm2

Height of the label = 20 - (2 x 2) = 20 - 4 = 16

Area of the label = 2πrh

= 2 x 22/7 x 7 x 16

= 704 cm2

Hence, area of the label is 704 cm2.
