Question

A company packages its product cylinder container whose base has a diameter of 17.5cm and height 32 cm. Company places a label around the surface of the container. If the label is placed 3cm from the top and 4cm from the bottom, find the area of the label.​

Answer 1

$curved \: surface \: area \\ = 2\pi \: rh= 2\pi \: (17.5)(32) \\ = \frac{22}{7} \times 35 \times 32 = 22 \times 160 \\ area \: of \: the \: label \\ = 22(160) - (2\pi \: r)(3 + 4) \\ = 22(160) - 7(35) \times \frac{22}{7} \\ = 22(160 - 35) = 2750 \: {cm}^{2}$

Answer 2

Answer:

704 cm^2 is the answer

Step-by-step explanation:

Here the lable is a hollow cylinder with,

Diameter= 14 cm

Radius= 14/2= 7cm

Height= 20-2-2= 16cm

AREA OF LABEL= Curved Suface Area of Cylinder

2piRh

2pi * 7 * 16

2 * 22/7 *7* 16

2 * 22 * 16

44cm * 16cm

704cm^2.......

Hope it helps you
