Marbles of diameter 1.4cm are dropped into a beaker containing some water and are fully submerged.The diameter of the beaker is 7cm.Find how many marbles

have been dropped in it if water rises by 56cm.
please check whether the rise in water level is 56 or 5.6


diameter of marble= 1.4cm
radius =1.4/2=0.7cm
volume= 4πr^3
diameter of a beaker= 7cm
radius = 7/2=3.5cm
height of a beaker
(water level)=56cm
volume= πr^2h
number of marbles can be dropped=volume of beaker/volume of marble
