Required Answer:-
Given the ratio of radius and heights of a cylinder and a cone
- Ratio of radius = √3 : √2
- Ratio of heights = √2 : √3
Assuming the Radius be √3r & √2r since they are in a ratio and the heights be √2h & √3h are also in ratio. Now we know the formula for volume of a cylinder.
➙
And the volume of cone:
➙
Plugging the assumed values of radius and heights to find their volume ratios:
➙
This would be equals to:
➙
Now taking πr²h common from both numerator and denominator:
➙
πr²h will be cancelled. Hence our volume ratio will remain 3√2 : 2√3/3. Simplifying further.
➙ Ratio of their volumes:
