Question

If the diameter of each cylinder

formed by him is 12cm, then height

of each of them is-​

Answer 1

Answer:

Volume of cylindrical container=πR

2

H=π×6

×15=540π㎤

Let radius of base of conical portion be 'r', then diameter=2r

and height=2×2r=4r

10×volume of each cone=volume of container

⇒10[
