Question
The heights of 2 cones are same and the radii of their bases are in the ratio 2:3 , ratio of their volumes is
- 2:3
- 3:2
- 4:9
- 9:4
Hint:
Volume of a cone = (1/3)πr2h
The correct answer is: 4:9
We have given that
Height is same , Let height be h
radius ratio is 2:3
r1:r2 = 2:3
Therefore the if we compare the volumes of the cones
= 
= (
)2
= 
Therefore the correct option is c) 4 : 9.
)2Therefore the correct option is c) 4 : 9.
