Question

The circumference of a circle is 12.56 cm. What is the area? Use 3.14 for n.

Answer 1

Answer:

12.55

Step-by-step explanation:

To solve for area using circumference, use the formula:

$a=\frac{c^{2} }{4\pi }$

where a=area and c=circumference

We know the circumference is 12.56, so

$a=\frac{12.56^{2} }{4\pi }$

Once you plug this in and solve, you get 12.55 for the area.

Hope this helps! :]
