A company packages its milk powder in cylindrical container whose base

1.	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.
Answer» Height of the label = 20 cm − 2 cm − 2 cm = 16 cm Radius of the label = (14/2) cm = 7cm Label is in the form of a cylinder having its radius and height as 7 cm and 16 cm. Area of the label = 2π (Radius) (Height) = { 2 x (22/7) x 7 x16 } cm²= 704 cm²

Answer»

Height of the label = 20 cm − 2 cm − 2 cm = 16 cm

Radius of the label = (14/2) cm = 7cm

Label is in the form of a cylinder having its radius and height as 7 cm and 16 cm.

Area of the label = 2π (Radius) (Height)

= { 2 x (22/7) x 7 x16 } cm²= 704 cm²
