let it's radius and height are r and h . then it's volume will be 1/3πr^2h . now if the r and h are increased by 1% , then the new radius will be 101r/100 and new height will be 101r/100.
therefore it's new volume will become1/3π1030301r^2h .
therefore the percentage increase in it's volume will be 3%
answer is 3%
