-------------------------------------------

let the radius is 'r' for cone, hemisphere and a cylinder..

THE RATIO OF THEIR VOLUME :

volume of cone : volume of hemisphere : volume of cylinder

$\frac{1}{3} \pi {r}^{2} h \:$

is the volume of cone. ......(1)

volume of hemisphere

$\frac{2}{3} \pi {r}^{2} h$

.........(2)

volume of cylinder

$\pi {r}^{2} h \: \: \: \: \: . \: \: \: \: \: \: \: \: \: \: \: \: \: .....(3)$

by doing the ratio of the three equations

we obtain

1/3 : 2/3 : 1

by dividing all three ratios by 1/3

we obtain

1:2:3

thus the required ratio is

1:2:3
