Question

in a cylindrical vessel of radius 10 cm containing some water 9000 spherical balls are dropped which are completely immensed in water which raises the water level if each spherical balls is of radius 0.5cm then find the level of water in the vessel​

Answer 1

Explanation:

radius of cylinder = 10cm

radius of spherical balls = 0.5

volume of 9000 spherical balls = volume of cylinder

9000 × 4/3 πr^3

9000×4/3×22/7×5/10×5/10×5/10. (0.5 = 5/10)

33000 = volume of 9000 spherical balls

volume of cylinder = πr^2h

22/7 × 10 ×10 ×h = 33000

h = (33000 × 7) / (10 × 10 × 22)

h = 105
