help plzz anyone

anonymous · Answer

Because  $V = \pi r^2 h$, you can write ratio like that: $V_A:V_B = \pi r_A^2h_A:\pi r_B^2h_B = \boxed{r_A^2h_A:r_B^2h_B}$

$r_A$ is radius of cylinder A
$h_A$ is height of cylinder A
$r_B$ is radius of cylinder B
$h_B$ is height of cylinder B

Just plug in values and simplify
