What will be the percentage increase in the volume?
Statement I : A cube of ice is dip into 20 litre water
Statement II : If radius of a cylinder increases by 25% and height increases by 20%
Statement III : If the height of ice cube is 20 cm.
From II: Volume = πr 2 h So by successive formula, the increase in volume can be found First: rate 2 So 25 + 25 + (25)(25)/100 = 56.25% Next: 56.25 + 20 + (56.25) × (20)/100 = 87.5% (final increase in volume) From I and III: volume of given shape (cylinder, cube, cone) = 20 litre (initial volume). And ice cube of height 20 cm is dip into it. So after finding new volume or increase in volume after the ice cube is dipped, % increase in volume can be found.
