Question

A rectangular paper of width 15cm is rolled along its width any a cylinder of radius 20cm is formed . Find the volume of the cylinder (Take x=22/7)​

Answer 1

Answer:

r=20

width =15

volume of cylinder = πr2h

22/7×20×20×15

=18,857.1429cm3

Answer 2

Answer:

17600 cm^3

Step-by-step explanation:

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 = πr^2h ,

Volume of a given cylinder = 22/7 x 20 x 20× 14 = 22 x 20 x 20x 2 = 17600 cm^3. ( Ans )
