Question

A rectangular paper of width 14 cm is rolled along with its width and a cylinder of radius 20 cm is formed. Find the volume of the cylinder

Answer 1

radius = 20cm
height = width = 14cm

Volume = πr^2h
➡ 22/7 * (20)^2 * 14
➡ 22 * 400 * 2
➡ 17600cm^3

Answer 2

Answer:

The volume of the cylinder is $17600 \: cm {}^{3}$

Step-by-step explanation:

Buy rolling the given rectangular paper along its with we obtain a cylinder of radius 20 cm and height 14 cm

∴ r = 20 cm and h = 14 cm

Volume of the cylinder = $\pi \: r {}^{2}h \: cubic \: units$

= $( \frac{22}{7} \times 20 \times 20 \times 14) \: cm {}^{3}$

= $17600 \: cm {}^{3}$

Hence, the volume of the cylinder is $17600 \: cm {}^{3}$
