# A conical flask is full of water. The flask has base-radius r and height h. The water is poured into a cylindrical flask of base-radius *m*r. Find the height of water in the cylindrical flask.

Answer :

Radius of the conical flask = r

Height of the conical flask = h

Radius of the cylindrical flask (R) =

Height of water in the cylindrical flask =

=

=

= .

Height of the conical flask = h

Radius of the cylindrical flask (R) =

*m*rHeight of water in the cylindrical flask =

=
