Question

A rectangular sheet of paper of dimensions 44 cm $\times$ 18 cm is rolled once along its length and a cylinder is formed. Find the volume of the cylinder so formed.

• A. $2700c{m}^3$
• B. $2772c{m}^3$
• C. $2800c{m}^3$
• D. $2900c{m}^3$

Answer 1

The correct option is B

$2772c{m}^3$

The paper is rolled once along its length, therefore, 44 cm forms the circumference of the base of the cylinder

$2\pi r=44$

r = 7 cm

Hence, Volume of the cylinder =$\pi r^{2}h$

= $\frac{22}{7}\times 7^2\times 18$

= 2772 $c{m}^3$
