A cylindrical vessel of diameter 32 cm is partially filled with water. A solid metallic sphere of radius 12 cm is dropped into it. what will be the increase in the level of water in the vessel ( in cm)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 9
The volume of the sphere = volume of water in the cylinder which will be shifted after dropping the sphere
4/3 πr³ = π r³ h ( where h = increase in the level of water )
4/3 (22/7) 123 = (22/7) 162 h
h = 9 cm
