Question

150 sperical Marbles each of radius 1.4 CM are dropped in a cylindrical vessel of radius 7 cm containing some water which are completely immersed in water find the rise in the level of water in the vessel​

Answer 1

Answer:

11.2 cm (hopefully I am right)

Step-by-step explanation:

For Marble,

Radius of each Marble, r = 1.4 cm

Volume of each Marble = (4/3)πr³

No. of Marbles = 150

For Cylinder,

Radius of Cylinder, R = 7 cm

Let the increase in height of water level be H cm

Volume of Cylinder after the Marbles are dropped = πR²H

According to Question,

4/3πr³ * 150 = πR²H

⇒ H = 4r³*150÷3R²

Substitute in the values and you will get the answer
