Answer:

Correct choice is A

Explanation:

The volume of the cylinder can be calculated using formula


V=\pi r^2 h,

where r is the base circle radius and h is the height of the cylinder.

In your case,
V=86.21\ ft^3,\ \ \ r=2.8\ ft,

then


86.21=\pi\cdot (2.8)^2\cdot h,\\ \\h=(86.21)/(7.84\pi)\approx (86.21)/(7.84\cdot 3.14)\approx 3.5\ ft.
