A cylindrical drum whose base is horizontal and having an internal rad
Right Answer is: C
In the cylinder of radius 6 cm, the sphere just fits. So, radius of spherical ball is 6cm.
Let, If spherical ball is put in the cylindrical drum, it raises water level by
So, volume of water raised in cylindrical drum = volume of sphere
So, The depth of water in the cylindrical drum before the spherical ball was put = 12-8 = 4cm
