Answer:
12.55
Step-by-step explanation:
To solve for area using circumference, use the formula:
[tex]a=\frac{c^{2} }{4\pi }[/tex]
where a=area and c=circumference
We know the circumference is 12.56, so
[tex]a=\frac{12.56^{2} }{4\pi }[/tex]
Once you plug this in and solve, you get 12.55 for the area.
Hope this helps! :]
