Question

A solid cylinder is melted and cast into a cone of same radius.The heights of the cone and cylinder are in the ratio


  1. 1:3

  2. 9:1

  3. 1:9

  4. 3:1


Solution

The correct option is D

3:1


Let r be the radius and h be the height of cylinder, then volume=πr2h

Now volume of cone=πr2h and r is the radius.

 Height (h)=Volume×3πr2=πr2h×3πr2=3h Ratio between their heights=3h:h=3:1
