How do you change square feet into a diameter of a cicle?

To find the diameter of a circle given the area. The area of a circle = pi x the radius squared. To find the radius, then the diameter transpose the area formula, so A = Π * r^2 A/ Π = r^2 √A/ Π= r 2 x √A/ Π = d A = area Π = pi = 3.142 r = radius d = diameter
