# A sphere of diameter 15.6 cm is melted and cast into a right circular cone of height 31.2 cm. Find the diameter of the base of the cone.

Answer :

Given,

When we convert any object into another shape the volume will remain same.

Radius of sphere =

Radius of cone = r cm

Volume of sphere = volume of cone

r^{2} = 60.84

r = 7.8cm

d = 2 × r = 2 × 7.8 =15.6 cm
