A rectangular sheet of size 22 cm × 10 cm is folded along its length to form a cylinder. Find the volume of the cylinder formed in ${c m}^{3}$ .

Open in App

Solution

Since the rectangular sheet is rolled along its length,

We have Cirumference of the cylinder = Length of the rectangular sheet

2 $π$ r = 22

$\Rightarrow$ r = 3.5 cm

Height of cylinder = breadth of the rectangular sheet

$\Rightarrow$ h = 10cm

Volume = $π$ $r^{2}$ h = 385 ${c m}^{3}$
