Radius of sphere = 4.2 cm
Radius of cylinder = 6 cm
Given that the object formed by recasting the hemisphere will be the same in volume.
Hence, Volume of Sphere = Volume of Cylinder.
(4/3)πr3 = πr2h
(4/3)π(4.2)3 = π(6)2h
Therefore, h = (1.4)3
h = 2.744 cm.
Hence, the height of the cylinder is 2.744 cm.
