Hey guys can yall help me out this is part of my final and my teacher hasnt taught us this -.- thank you

Step-by-step explanation:

First, lets find the volume of both of them individually,

The formula for this is V=πr²h (V = volume, r = radius, h = height)

Lets do cylinder A first! Simply plug in your numbers

V = 3.14 · 3² · 4

V = 3.14 · 9 · 4

V = 113.04          this is the volume of cylinder A

Repeat these steps for cylinder B

V = 3.14 · 5² · 2

V = 3.14 · 25 · 2

V = 157

Without simplifying, the ratio is

With simplifying, your answer is A,

Hope this helps!
