Question

a rectangular paper of with 14 cm is rolled along its length and a cylinder of radius 20 cm is formed find the volume of cylinder ( take π = 22/7 )

Answer 1

Given : A rectangular paper of width 14 cm is rolled along its width to form a cylinder . So

Height of cylinder = h = 14 cm = width of the rectangular paper

And
Radius of cylinder ( Given ) = r = 20 cm

And
we know Volume of cylinder = π r2 h , So

Volume of our given cylinder = 22/7× 20 × 20× 14 = 22× 20 × 20× 2 = 17600 cm3 ( Ans )
