Question

A rectangular paper of length 14 cm is rolled along its width and a cylinder

of radius 20 cm is formed. Find the volume of the cylinder.​

Answer 1

17600cm³

Step-by-step explanation:

Volume of cylinder = πr²h

=

$\frac{22}{7} \times 20 \times 20 \times 14 \\ = 22 \times 20 \times 20 \times 2 \\ = 17600 {cm}^{3}$

Answer 2

Answer:

l = 14cm

h = 14cm

r = 20cm

$v = \pi \: r^{2} h$

v = 22/7 × (20)² × 14

v = 22 × 400 × 2

v = 44 × 400

v = 17600cm³
