Solution
The number of balls of radius 2 cm that can be made from a sphere of radius 6 cm, is 27.
Explanation:
The number of small balls formed is equal to the volume of the large sphere divided by the volume of one small ball. Since volume is proportional to the cube of the radius, the calculation is `(6/2)^3`
= `3^3`
= 27 balls
