The area of a circle S bounded by a circle of radius R is determined by the formula S = п * R ^ 2. п = 3.14. Since the diameter D is two radii, then R = D / 2. Let us express the area of the circle in terms of the diameter of the circle S = п * (D / 2) ^ 2 = п * D ^ 2/4. Find S = 3.14 * 64/4 = 50.24 cm ^ 2.
Answer: S = 50.24 cm ^ 2.
