Q5 of 44 Page 14

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.

Given that Radius of cone = 12cm


Height of the cone = 24cm


So,




= 1152π cm3


It is also given that diameter of each spherical balls = 6cm


so, Radius of each ball = 3cm




= 36π cm3


Total number of balls formed by melting the cone




= 32


Hence, 32 balls are formed by melting the cone.
