A rectangular paper of width 7 cm is rolled along its width and a cylinder of a radius 9 cm is formed. The volume of the cylinder is:(Take $π =\frac{22}{7}$)

1782 cm³

We know that,

Volume of the cylinder = πr²h

We have,

The radius of the cylinder r = 9 cm

Height of the cylinder h = 7 cm

Volume of the cylinder =  \(\frac{22}{7}\) × 9 × 9 × 7 = 1782 cm²
