the height of cylinder filled is 3 cm
HimanshuHK:
3 CM! How?
sorry 6cm
because 2/3πr³=πr²h
right
but how can we take them equal! hemisphere radius and cylinder radius are different.. !

volume of Hemisphere=2/3 πr³
=2/3π 9*9*9
=486π
Volume of cylinder= πr²h
but volume which us filled is given that is 486π
so πr²h=486π
r²h=486
36h=486 (r=6)
h=486/36
h=13.5
so Height is 13.5 centimetres!
