# 150 spherical mar

Given,

Diameter of marble = 1.4 cm

Radius of marble = 0.7 cm

Number of marbles = 150

Diameter of cylinder = 7cm

150 × Volume of spherical marbles = volume of cylindrical vessel
150 x × π × 0.7 × 0.7 × 0.7 = π × 3.5 × 3.5 × h

50 x 4 x (0. 7)3 = (3.5)2 x h

200 x 0.343 = 12.25 x h

= 5.6 = h

So,

h = 5.6 cm

The rise in the level of water in the vessel (h) = 5.6 cm
