and the circumference of a circle is 
or 
so since we know that the circumference is 
we can take the diameter from that to find the radius. The radius is half of the diameter,so in our case 3.5. Now use this to find area. 3.5 times 3.5 is 12.25. So the exact area is 
There are different ways than this to solve the problem. For example you could also use the method I attached as a reference.
