Question

A Spherical cannon ball 6cm in diameter is melted and cast into conical mould the base of which is 12cm in diameter find the height of a cone​

Answer 1

Answer:

0.75 cm

Step-by-step explanation:

Let h= height of cone

Since the spherical ball is melted and recast into cone, so

Volume of spherical ball = Volume of cone

πd^3/6=1/3πr^2h

6^3/6=1/3*12^2*h

h=0.75 cm
