12 solid spheres of the same radii are made by melting a solid metallic cylinder of base diameter 2cm and height 16cm. Find the diameter of theeach sphere.​

Answer»

Volume of a sphere of radius 'r' = 34 πr 3 Volume of a Cylinder of Radius "R" and height "h" =πR 2 hAs the DIAMETER of the cylinder is 2 CM, its radius r =1 cmNow, Volume of 12 spheres = Volume of the cylinder.12× 34 πr 3 =π×1 2 ×16r 3 =1r=1cmHence, diameter of the sphere =2cm
