The area of a circle that has a circumference of 18 is 25.78 inches squared.
Approximately 86.7 units squared.
The circumfrence is like a perimeter. It is the area around a circle. You can find the circumfrence of a circle by using this formula. Pi x R2 or Pi times the radius squared.

The circumference of a circle is (diameter) multiplied by (pi).

The area of a circle that has a circumference of 18 is 25.78 inches squared.
The circumfrence; Pi (or 3.14) times the width across the circle :)
Approximately 86.7 units squared.
It depends on what information you have: radius, diameter, lengths of tangents from a point outside the circle, length of chord and its distance from the centre, etc. Also, the term is circumference, not circumfrence.

divide
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
Circumfrence
If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.
the circumfrence of a circle is pi times it's radius squared.
