Question

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.

Answer 1

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.
