Question

a rectangular sheet of paper 44cm*20cm, is rolled along its length to form a cylinder. Find the volume of the cylinder so formed​

Answer 1

Answer:

length of rectangular = height of cylinder

breadth of rectangular = diameter of cylinder

so,

height of cylinder=44cm

radius of cylinder =20/2=10cm

$volume \: of \: cylinder = \pi {r}^{2} h$

volume of cylinder = 3.14×10×10×44

volume of cylinder = 314×44

volume of cylinder = 13816cm cube
