A hollow sphere of internal and external diameters 4 cm and 8 cm respectively is melted and cast into a cone of base diameter 8 cm. Find the height of the cone.
Asked by Topperlearning User | 27 Oct, 2017, 03:00: PM
Expert Answer
External diameter of sphere = 8 cm radius, R = 4 cm
Internal diameter of sphere = 4 cm radius, r = 2 cm
Diameter of the base of cone = 8 cm radius = 4 cm
Now, Volume of the cone = Volume of the material in the sphere
Hence, the height of the cone = 14 cm
