Answer: 1:9
Explanation:
The volume of cylinder is given by :-
, where r is radius and h is height of the cylinder.
For cylinder A
radius = 1 m
height =3 m

For cylinder B
radius = 3 m
height =3 m

Now, the ratio of the volume of cylinder A to the volume of cylinder B is given by :-

Hence, the ratio of the volume of cylinder A to the volume of cylinder B is 1:9.
