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
r2 = 60.84
r = 7.8cm
d = 2 × r = 2 × 7.8 =15.6 cm
