Circumference, C = 2*Pi*R Area, A = Pi * R^2 A = C Pi * R^2 = 2*Pi*R --> solve for R (radius) R = 2 So, the radius of a circle with area = circumference is two.

Area = pi*r2 = 2*pi*r = circumference then r2 = 2r so that r = 2
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, 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.
True. The diameter of a circle is always twice the length of the radius. In other words, if we denote the radius of a circle as "r," then the diameter can be expressed as "2r." This relationship holds true for all circles, regardless of their size.
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.

The circumference is (2 pi) times (the radius), and the area is (pi) times (the radius squared).The same statements are true for any circle, not only this one, so this is actuallyquite a powerful answer.
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. The circumference is the distance round the outer edge of the circle, calculkated as 2 x pi x the radius.The area is calculated as pi x the square of the radius.
Frankly, I haven't the slightest clue as to what you mean by "the same." The circumference of a circle is defined as pi x 2 x radius, or pi x diameter. The area is pi x radius squared. Therefore, for real circles, these values can only be the same if the diameter measure is the same as the radius squared. This works is the radius is 1 or 2.
The volume is Base x height; the Base area is the same as the formula for a circle - which is proportional to the square of the radius. For example, if you double the radius (or the diameter, or the circumference) of a circle, its area will quadruple.
The circumference of a circle if the radius is 18 is: 113i have the same question and its multiple choice and none of the choices say 113! :((
Assuming you are talking about the circumference of a circle, then the answer, briefly, is no. The circumference of a circle is determined by multiplying the length of the diameter by pi (π). The diameter of a circle is twice its radius.
No,Circumference is like the perimiter and Area is the whole circle.
The circumference is the distance AROUND a circle. The diameter is the distance ACROSS a circle. The radius is the the distance FROM THE CENTER of the circle (same thing as one-half of the diameter).
Area = pi*r2 = 2*pi*r = circumference then r2 = 2r so that r = 2
