Question

A square sheet of paper is 44 cm long is rolled along its length to form a cylinder find the volume of the cylinder so formed​

Answer 1

$\sf \: Volume \: of \: a\: cylinder \: = \: 2 \: \pi \: {r}^{2} h$

Substituting the values,

$\sf \: Volume \: of \: a\: cylinder \: = \: 2 \: \times \: \frac{22}{7} \: \times \: {7}^{2} \: \times \: 44$

$\sf \: Volume \: of \: a\: cylinder \: = \: {13552 \: cm}^{3}$
