Question

The `3/4` th part of a conical vessel of internal radius 5 cm and height 24 cm is full of water. The water is emptied into a cylindrical vessel with internal radius 10 cm. Find the height of water in cylindrical vessel. 

Solution

Radius of conical vessel r = 5 cm

Height of conical vessel h = 24 cm

The volume of water = `3/4` ×volume of conical vessel

`= 3/4 xx 1/3 pir^2h`

`3/4 xx 1/3 pi xx 25 xx 24`

= 150

Let h' be the height of cylindrical vessel, which filled by the water of conical vessel,

Radius of cylindrical vessel = 10 cm

Clearly,

Volume of cylindrical vessel = volume of water

`pi(10)^2h = 150`

=> h = 1.5 cm

Thus, the height of cylindrical vessel is 1.5 cm.

  Is there an error in this question or solution?
