AI explanation

The radius is found by dividing the circumference by twice pi, yielding 113.6 divided by 6.28, which is approximately 18.08 cm. The area of a circle is pi times the radius squared, so we multiply 3.14 by approximately 326.9 to get 1028.466 sq cm. The area is approximately 1028.7 cm2.
