C=2(pi)r A=(pi)r2 If C=A, then 2(pi)r=(pi)r2. Divide both sides by r: 2(pi)=(pi)r. Divide both sides by (pi): 2=r. Therefore, if the radius of a circle is 2 ft., the circumference is 2 sq. ft.

No,Circumference is like the perimiter and Area is the whole circle.
196 feet of course. For a circle "perimeter" and "circumference" are just two words for the same thing.
The circumference is not always 3.14 , The circumference of a circle is always (pi) times as long as the circle's diameter. (Pi) is a number that can't be exactly written down with digits, that begins with 3.14 . It's defined as the ratio of any circle's circumference to the same circle's diameter. The reason is because that's one of the properties of the thing that we call a "circle".
You didn't specify what figure you are talking about; the circumference or perimeter is different for different objects of the same size. For example, an elongated ellipse will have less area for the same circumference, as compared to a circle.Assuming a circle: First get the radius, as 32 / (2 * pi) = 5.0930. Next use the formula area = pi * r squared = pi * 5.0930 squared = 81.487 (square units).
Pi is the mathematical term for the ratio of the circumference of a circle to its diameter. If you divide the circumference of any circle by its diameter you will get exactly the same answer which is approximately 3.14.
