Question

A solid right circular cone of height 60 cm and radius 30 cm is dropped in a right circular cylinder full of water of height 180 cm and radius 60 cm find the volume of water life in the cylinder in cubic metre

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Here is ur answer :

Given, 

Height h of cone = 60 cm

Radius r of cone = 30 cm

Volume of cone 

1/3πr2=18000π cm3
_________________

For cylinder 

Height h of cylinder = 180 cm

Radius r of cylinder = 60 cm

Volume of cylinder 


πr2h=648000cm3



When we drop the cone inside the cylinder which is full of water, then 

Volume of water flows out = Volume of cone. 


Volume of water that is left in cylinder 

= Volume of cylinder — Volume of cone


648000π-18000π

=63000π


=63000*22/7

=198000

=1cm3=1-6m3

=198000cm3=0.198m3


Therfore, 

Volume water left in the cylinder = 0.198 m³
