The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter. We are given that the circumference is 56.52 inches. We can plug this into the formula and solve for d:
56.52 = 3.14d
Dividing both sides by 3.14:
d = 56.52/3.14
d ≈ 18 inches
Therefore, the diameter of the flag is approximately 18 inches.
