A solid metal cylinder of radius 14cm and height 21cm is melted and recast into spheres, each of radius 3.5 cm.calculate the no of spheres that can be



Let no, of spheres be N
by given,volume of the cylinder=NxVolume of spere
radius of cylindr=14cm
height of cylinder=21cm
volume=πr²h  =22/7 x 21 x 14 x 14
                       =12936 cm³
radius of sphere=3.5cm
volume=4/3πr³  =4/3 x 22/7 x 3.5 x 3.5 x 3.5
thus 72 spheres can be made
