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".

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.

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).

They can't have the same value, since area has square units and circumference has linear units. But their number portions can be the same. The circumference and the area of a circle with a radius of 2 are both (4 pi), with the appropriate units.

No,Circumference is like the perimiter and Area is the whole circle.

The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.

No

The area of a circle is the amount of space inside the circle. The circumference of a circle is the distance around the outside of the circle. (So no, they are not the same thing.)

No. A circle's area is a two dimensional concept while its circumference is one dimensional. Having said that, a circle's area and circumference can have the same numerical value. Area = pi*r2 Circumference = 2*pi*r So if pi*r2 = 2*pi*r, that is to say, if r = 2 units both will have the same numerical value.

No, because the circumference is a linear measure whereas the area is a square measure. However, they can have the same numerical value. If a circle has radius r cm, its circumference is 2*pi*r cm while its area is pi*r2 cm2. These two are numerically equal if 2*pi*r = pi*r2 that is, r = 2 when both measures are 4*pi = 12.6 approx. The fact that the dimensions are different means that, in other units (inches for example) the same circle will not have equal circumference and area. In this case, the circle has a circumference of 4.9 inches and an area of 1.9 sq inches: not the same.

No, the two are quite different things.

The area of a circle with a radius of 18.4 feet is approximately 1,061 square feet. The circumference of the same circle is approximately 115.7 feet.

no, the cimcumference is the perimeter of the circle and the area included what is inside of the circle, area can be used for all shapes

Area of a circle is: A=π*r2 and r=circumference/2. Find 1/2 of the circumference and square it (multiply by same number), then multiply by pi.
