A metallic spherical shell of internal and external diameters 4 cm and 8 cm respectively is melted and recast into the form a cone of base diameter 8 cm The height of the cone is

Text Solution

Verified by Experts

Given that volume of cone = volume of sphere
`1/3pir1^2h=4/3pi(R^3-r^3)`
`16h=4(4^3-2^3)`
`4h=56`
`h=14cm`
