150 spherical marbles, each of diameter 1.4 cm are dropped in a cylindrical vessel of diameter 7 cm containing some water, which are completely immersed in water. Find the rise in the level of water in the vessel.

Answer :

Diameter of spherical marbles cm

=0.7 cm

Diameter of cylinder vessel

=3.5 cm

Volume of 150 spherical balls =150× 3


=215.6 cm3

Let the rise in level of water be h cm

Volume of rise in level of water (Volume of cylinder )

Volume of Rise in level of water in the vessel =volume of 150 spherical balls

(22/7) × 3.5 × 3.5 × h = 215.6

h = 5.6 cm
