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

Answer 2

Answer:

Let the height of the cone be h.

Volume of cylinder = Volume of cone

⇒πr²(5)=13πr²h

⇒h=15 cm
