Answer:
The ratio of the volume of cylinder a to the volume of cylinder b is 1 : 2 .
Step-by-step explanation:
We know that,
The volume of a cylinder is,

Where, r is the radius of the cylinder,
h is the height of the cylinder,
Given,
For cylinder a,
r = 1 m and h = 4 m
Thus, the volume of the cylinder a is,


Now, for cylinder b,
r = 1 m and h = 8 m
Thus, the volume of the cylinder b is,


Hence, the ratio of the volume of cylinder a to the volume of cylinder b is,
