Question

A rectangular paper of size 22×14 cm is rolled to form a cylinder of height 14 cm, find the volume of cylinder.

Answer 1

i.e 2Πr=14cm

=> r=14/2Π cm

The formula for calculation of volume is

V=Πr^2h

You got the value of r and h and hence can easily calculate the volume.

I hope this is helpful. :)
