Answer: B. 1256 cm2
area = 3.14 r^2
circumference = d * 3.14
To solve:
First we need to work backwards from the circumference to find the diameter- we start with 125.6 = 3.14 * d. We then divide by 3.14 to get 40 = d. Divide by 2 to get the radius and we get 20 cm. Then, we plug the radius into the area formula, getting us 3.14 * 20^2. 20^2 = 400, so we get 3.14 * 400. 3.14 * 400 = 1256, so the area is 1256 cm2.
Hope this helped
