**A company packages its milk powder in a cylindrical container whose base has a diameter of 14 cm and a height of 20 cm. The 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:

Given,

Diameter of cylindrical container = 14 cm

So, radius (r) = 14/2 = 7 cm

And, height (h) = 20 cm

Now,

Width of label = 2 0 – (2 + 2) cm = 20 – 4 = 16 cm

Hence, area of label = 2πrh

= 2 × (22/7) × 7 × 16

= 704 cm^{2}
