Question

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

Answer 1

12.55

Explanation:

To solve for area using circumference, use the formula:

`a=(c^(2) )/(4\pi )`

where a=area and c=circumference

We know the circumference is 12.56, so

`a=(12.56^(2) )/(4\pi )`

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

Hope this helps! :]
