The size of a rectangular piece of paper is 100 cm × 44 cm. A cylinder is formed by rolling the paper along its length. The volume of the cylinder is

Length of the rectangle if circumference of the base cylinder

$2\pi r=100cm\Rightarrow r=\frac{50}{\pi }cm$

height of the cylinder$h=breadthoftherec\text{tangle}=44cm$

volume of the cylinder $=\pi r^{2}h=\pi \times \frac{50}{\pi }\times \frac{50}{\pi }\times 44=\frac{7}{22}\times 50\times 50\times 44=35000c{m}^3$
