Well, honey, to find the area of a circle, you use the formula A = πr^2. Since the diameter is 8.5 inches, the radius is half of that, which is 4.25 inches. Plug that into the formula, and you get an area of approximately 56.77 square inches. Math doesn't lie, darling.

The answer above is correct. Here is the formula
Area of a circle = pi X r2
r = radius = 1/2 X diameter
pi = 3.1416
