A rectangular paper of which 7 cm is called along its width and a cyli

1.	A rectangular paper of which 7 cm is called along its width and a cylinder of radius 20 cm is formed. Find the volume of the cylinder.
Answer» 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 = 20 cm And we know Volume of cylinder = π r^2 h , So Volume of our given cylinder = 22/7 x 20 x 20 x 7 = 8800 cm^3 .Ans

A rectangular paper of which 7 cm is called along its width and a cylinder of radius 20 cm is formed. Find the volume of the cylinder.

Answer»

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 = 20 cm

And

we know Volume of cylinder = π r^2 h , So

Volume of our given cylinder = 22/7 x 20 x 20 x 7 = 8800 cm^3 .Ans
