where r is the radius of the cone
h is the height of the cone
and volume of a cylinder=
where r' is the radius of the cylinder
h' is the height of the cylinder
so as
So ratio of
(π on above and below i cancelled)
(1/(1/3)=3)(3²=9,4²=16)
3 above and below are cancelled
and then 16/2=8
Answer:
hope it's correct
