a volume puzzle please help?

[jainpreetham]

a cylinder is placed with its central axis parallel to the ground.Water is filled into it.a whole is made at the bottom(please note its not at 1 of the parallel plates).If the change in height of the water level is given
(height measured parallel to the 2 horizontal plates) how can i find the change in volume?


please help its pretty important and urgent!!!!

Let r be the radius of the end of the cylinder. The area of the end is then A = ?r² and if L is the length of the cylinder, then V = L*A.
Let h be the height of the water in the cylinder and calculate
s = h - r Then calculate the angle
? = arccos(s/r) Then the current volume v is
v = (?/180)*V

HTH ?
