A cylindrical tub of radius 20 cm A spherical ball is dropped
into the tub and the label of water is raised by 6 75 cm Find the
radius of ball ?

Hi!
We are assumed that, when the spherical ball is completely
immersed into the tub, the level of the water is raised by 6 75
cm
Therefore, it is clear that the volume of the ball is equal to
the volume of a cylinder of radius 20 cm and height 6 75 cm
