<PRE><B>Question 861749</B>
A connical funnel of diameter 23.2cm and depth of 42cm is full of water.If the water is poured into a cylinder tin of diamter 16.2cm find the least possible height of the tin if it must contain all the liquid.

A connical funnel of diameter 23.2cm , radius = 11.6 cm

and depth of 42cm = h

Volume of cone = 1/3 *pi*r^2*h
=1/3 * pi * 11.6^2*42
=1883.84pi

this is the volume of cylinder  r= 8.1

1883.84pi = pi *8.1^2*h

h= 1883.84/8.1^2

h=28.71 cm


If the water is poured into a cylinder tin of diamter 16.2cm find the least possible height of the tin if it must contain all the liquid.
