Answer:

A = 12.554 square inches

Step-by-step explanation:

Let's start with the formulas:  

Circumference = 2\pi r; Area = \pi r^{2}

We can use the circumference to find the radius, <em>r</em>, which we need for the area

12.56 = 2\pi r

Isolating <em>r</em> gives us \frac{12.56}{2\pi }  = r

A = \pi (\frac{12.56}{2\pi })^{2}

Solving gives us 12.554, which you can further round if necessary.
