The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.
Given that the area is 615.44 in^2, we can solve for the radius:
615.44 = 3.14 * r^2
615.44 / 3.14 = r^2
196 = r^2
r = √196 = 14
The diameter of a circle is twice the radius, so the diameter is:
2 * 14 = 28 in
Therefore, the diameter of the circle is 28 inches.
