Q4 of 227 Page 897

A solid metal cone with radius of base 12 cm and height 24 cm is melted to form solid spherical balls of diameter 6 cm each. Find the number of balls thus formed.

Let the number of balls formed = n


Since the metal cone is melted to form spherical balls;


So we have;


Volume of metal cone = Total volume of n spherical balls


Volume of cone = n(Volume of 1 spherical ball)







n = 32


So, 32 spherical balls can be formed.
