Question

the material of solid cone is converted into the shape of solid cylinder is equal radius if the height of the cylinder is 5 cm what is the height of cone

Answer 1

Since the volumes are equal.

 1/3πr²h1 = πr²h2

   πr² cancel from both the side.

   h1/3 = h2

∵ h2 = 5

∵ h1 = 3h2

      = 3×5

      = 15 cm
