Solid cylinder of brass 8m high and 4m diameter is melted and recast into a cone of diameter 3m. Find the height of the cone.

Explanation

Given,

Height of Solid cylinder= 8m

Diameter =4m

Radius of cylinder =`4/2=2m`

Radius of cone=`3/2=1.5 m`

Volume of cylinder=Volume of cone

=`pir^2h=1/3pir^2h`

=`2^2 xx 8=1/3 (1.5)^2 xx h`
