Question

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 1

Answer:

The area of the label is $704 \hspace {2mm} cm^2$

Step-by-step explanation:

Given:

Diameter of the base of the cylinder $d=14cm$

and Height of the of the cylinder $h=20cm$

The label is placed 2 cm from top and bottom.

Height of the label $=20-2-2=16 cm$

Radius of the base of the cylinder=

                                                            $\frac{Diameter }{2} =\frac{14}{2}\\ \\ Radius =7 cm$

We know that,

Area of the Curve surface area of the cylinder=$2\pi r h$

The curved surface area of a cylinder is=

                                                                       $2\cdot \frac{22}{7} \cdot 7 \cdot 16\\ \\ =44\cdot 16\\ \\ =704 \hspace {2mm}sq. cm$

Answer 2

Step-by-step explanation:

Hence the area of the label of 704 cm2. A company packages its milk powder in a cylindrical container whose base has a diameter of 14 cm and height 20 cm. The company places a label on 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?
