Question

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 the
each sphere.

Answer 1

Volume of a sphere of radius 'r' =

3

4

πr

3

Volume of a Cylinder of Radius "R" and height "h" =πR

2

h

As the diameter of the cylinder is 2 cm, its radius r =1 cm

Now, Volume of 12 spheres = Volume of the cylinder.
