HELP PLEASE

Answer:
Step-by-step explanation:
Volume of cylinder formula:
Find r by substituting given values:
Correct choice is A.
Answer:
radius, r = 4 meters
Volume of cylinder:
Here provided with:
Substituting these values in the formula:
[tex]\sf \rightarrow \pi (r)^2 (4) = 64\pi[/tex]
[tex]\sf \rightarrow 4\pi (r)^2 = 64\pi[/tex]
[tex]\sf \rightarrow r^2 = 64\pi /4\pi[/tex]
[tex]\sf \rightarrow r^2 =16[/tex]
[tex]\sf \rightarrow r=\sqrt{16} = 4[/tex]
