Question

Ramu says that if a cone is melted and recast into a cylinder then volume of a cone is equal to volume of a cylinder do you agree with him give reason​

Answer 1

Answer:

If the height of the cylinder =7cm then its volume is V=πr

2

h=7πr

2

where h=7cm

Cone has the same volume as that of the cylinder.

∴

3

πr

2

h

=7πr

2

⇒

3

h

=7 on simplification

∴h=21cm
