the diameter and height have increased of a can by 10% how much has the volume increase?
:
radius is also increased by 10%
therefore New vol:Old vol
%28pi%2A%281.1r%29%5E2%2A1.1h%29%2F%28pi%2Ar%5E2%2Ah%29 = %28pi%2A1.21%2Ar%5E2%2A1.1h%29%2F%28pi%2Ar%5E2%2Ah%29
cancel pi, r^2 and h
%281.21%2A1.1%29%2F1 = 1.331, vol increases by 33%
