A sphere of diameter 18 cm is dropped into a cylindrical vessel of diameter 36 cm , partly filled with water . If the sphere is completely submerged then the water level rises by

A

3 cm

B

4 cm

C

5 cm

D

6 cm

Text Solution

Verified by Experts

The correct Answer is:
A
Increase in volume of water= volume of the sphere
`rArr pi xx 18 xx 18 xx h =4/3 pi xx 9xx9xx9 rArr h=(4/3 xx (9xx 9xx9)/(18xx 18))cm = 3 cm `
