See below

Cylinder A: $V=S_bxxh$ where $S_b$ is the base surface and $h$ is the height

Then $V_A=pi·1^1·3=3pi$

Cylinder B. The same calculation process

$V_B=pi·3^2·3=27pi$

Then $V_B/V_A=(27pi)/(3pi)=9$ or if you want $V_A/V_B=1/9$

The relationship is 1:9

$1:9$

volume of cylinder $=pir^2h$

$V_A=pixx1^2xx3$

$V_A=3pi$

$V_B=pixx3^2xx3$

$V_B=27pi$

$V_A:V_B::3pi:27pi$

$=>V_A:V_B::1:9$
