Question

a rectangular piece of paper 44 cm long and 21 CM broad is rolled along its length to form a cylinder find the volume of the cylinder thus formed​

Answer 1

Answer:

3234 $cm^{3}$

Step-by-step explanation:

Length of the paper becomes base circumference of the cylinder.

=> 44 = 2πr = 2 x $\frac{22}{7}$ x r => r = 7 cm

Breadth of the paper becomes the height of the cylinder.

=> h = 21 cm

Volume of cylinder = π x $r^{2}$ x h = $\frac{22}{7}$ x 7 x 7 x 21

                                                   = 3234  $cm^{3}$
