The area of the whole circular cookie cake can be calculated using the formula:
A = πr^2
where r is the radius of the circle. We know that the diameter of the circle is 16 inches, so the radius is half of that, or 8 inches. Substituting into the formula:
A = 3.14 * 8^2
A = 3.14 * 64
A ≈ 200.96
So, the area of the whole cookie cake is approximately 200.96 square inches.
To find the area of half of the cookie cake, we can divide the area by 2:
A_half = 200.96 / 2
A_half = 100.48
Therefore, half of the cookie cake is approximately 100.48 square inches. So, the answer is 100.48 square inches.
