A solid sphere of radius 3cm is melted and then cast into small spherical balls each of diameter 0.6cm. Find the number of balls thus obtained.

Explanation

Let the number of balls `x`


Volume of the solid sphere`=4/3pi r^3=4/3 pi X3^3cm^3=36 pi cm^3`


Radius of spherical ball=`0.6/2cm=0.3m`


Volume of the spherical ball`=4/3 pi X(0.3)^3 cm^3`
