The volume of a cylinder is defined by the formula:
V = π r ² h
V = (π d² h)/4
since you are asked of the diameter, we will use the formula involving diameter
given: V = 320π ft³
             h = 20 ft
substitute to the formula
V = (πd²h)/4
320π = (πd²(20))/4
 d² = 320(4)/20
d² = 64 ft²
d = 8 ft
therefore the diameter is 8ft
