Question

A rectangular sheet of paper 55 cm x 23 cm is rolled along its length and a cylinder is formed. Find the volume of the cylinder.

Answer 1

Answer:

Height of cylinder = Width of sheet =23 cm

Circumference of top = 2πr = Length of sheet =55 cm

⇒r=  55/ 2 π  =35/4 cm

Now, volume = πr^2 h

         = 22/7 * (35/4)^2 * 23

        = 5534.375  cm^3

Answer 2

Answer:

Height of cylinder = width of sheet BC =23cm

Circumstance of top=2πr = Length of sheet AB=55 cm

r=55/2π

Now, volume = πr^2h

π(36/2π)^2 *23

55*55*7*23/4*22=5*55*7*23/4*2= 5534.375 cm^3
