This is easy to understand if u know Archimedes principle
Even if u don't,
Understand this:
Amount of volume rise in water = Volume of cylinder
As water is a liquid and takes the shape of the container
it's volume is considered to be cylindrical
Volume of water risen=Volume of cylinder immersed
π*7.2*7.2*5=π*4*4*h
H=16.2
Height of cylinder immersed is 16.2cm
