Answer:
The answer is the option A
\(816.81\ ft^{3}\)
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
\(V=\pi r^{2} h\)
where
r is the radius of the cylinder
h is the height of the cylinder
In this problem we have
\(r=4/2=2\ ft, h=65\ ft\)
substitute the values
\(V=\pi(2)^{2}(65)=816.81\ ft^{3}\)
