Q. 15. Raffie uses a circular cookie cutter with a diameter of 1 inch to cut four cookie shapes out'of a 2-inch square sheet of dough. Exrctly how many square inches of dough are left over?
Calculate Square Dough Area: First, calculate the area of the 2-inch square sheet of dough.Area of a square = side length × side length.Area = 2 inches ×2 inches = 4 square inches.
Calculate Cookie Area: Next, calculate the area of one cookie. Since the diameter of the cookie cutter is 1 inch, the radius is half of that, which is 0.5 inches. Area of a circle = π×radius2. Area of one cookie = π×(0.5 inches)2=π×0.25 square inches.
Calculate Total Cookie Area: Now, calculate the total area of four cookies.Total area of four cookies = 4×(π×0.25 square inches)=π square inches.
