Visually, area of the label on the cylinder will be equal to the lateral surface area of the container excluding the area covered by 2 cm gaps from top and bottom.
Height of the label h = 20 cm - 2 × 2 cm = 16 cm [Subtracting the 2 cm gaps from top and bottom]
Radius of the label = 14/2 cm = 7 cm
Label is in the form of a cylinder having its radius and height as 7 cm an 16 cm respectively.
Area of the label = Lateral surface area of the cylinder = 2πrh
= 2 × 22/7 × 7 cm × 16 cm
= 704 cm²
Thus, the area of the label is 704 cm².
