Question

A cylinderical bucket with base radius 15cm filled with water up to a height of 20 cm.a heavy iron spherical ball of radius 9cm is dropped into the bucket to submerge completely in the water .find the increase in the level of water

Answer 1

Given, Radius of cylindrical bucket (r) = 15 cm

And, height of water level (h) = 20 cm

And, radius of spherical ball (R) = 9 cm

Now, spherical ball is dropped into the bucket.

So, let the height of water level raise = h cm

Therefore,



Substitute all the given values in above equation, we have,



Hence, water level is increased by 4.32 cm.
