Question

the radius of a solid sphere is 12cm.How many spheres can be made from it of 6cm

Answer 1

Let R=12cm And r=6cm Volume of Sphere equal to 4/3πr^3  so volume of largest so volume of larger sphere =4/3π(12)^3 Similarly volume of smaller sphere  =4/3π(6)^3 Dividing volume of larger sphere by smaller sphere  We get. 8  So 8 sphere of 6cm  can be made from the sphere of radius 12cm
