Given : A rectangular paper of width 14 cm is rolled along its width to form a cylinder.
Height of cylinder = h = 7 cm = width of the rectangular paper
And
Radius of cylinder ( Given ) = r = 10 cm
And
we know Volume of cylinder = π r^2 h , So
Volume of our given cylinder = 22/7 x 10 x 10 x 7 = 2200 cm^3
Height of cylinder = h = 7 cm = width of the rectangular paper
And
Radius of cylinder ( Given ) = r = 10 cm
And
we know Volume of cylinder = π r^2 h , So
Volume of our given cylinder = 22/7 x 10 x 10 x 7 = 2200 cm^3
