Help me out? Please and thank you so much

Answer:
C) the volume of cylinder B is 5 times the volume of cylinder A
Explanation:
By inspection of the diagram we can see that the radius of both cylinders are the same and the heights are different, so we can automatically discount answer options A and D.
Volume of a cylinder = [tex]\pi r^2h[/tex]
⇒ volume of A = 100[tex]\pi[/tex] cm³
⇒ volume of B = 500[tex]\pi[/tex] cm³
500[tex]\pi[/tex] ÷ 100[tex]\pi[/tex] = 5
Therefore, the volume of cylinder B is 5 times the volume of cylinder A
