Let the original radius and height be r and h, respectively.
So, the volume of cylinder =πr2h .......(1)
Since, the radius and height are each increased by 10%, then
The new radius =1.1r and new height =1.1h.
Therefore, the new volume of the cylinder will be
=π(1.1r)2×(1.1h)
=1.331×πr2h .........(2)
Therefore, the required percentage
=1.331πr2h−πr2hπr2h×100
=0.331πr2hπr2h×100
=33.1%
Hence, this is the answer.
