How can the distance around a circle be the same as the area inside a circle?
It cannot be because the first is a measure of length whereas the second is a measure of area. Basic rules of dimensional analyses states that such comparisons are meaningless.However, the numerical value of the circumference of a circle and the numerical value of its area will be the same if the radius has a value of 2 in some measurement units.A circle with radius of 10 cm has a circumference of 63 cm and an area of 314 cm^2 and these are clearly not equal. But if the measurements are taken in units of 5 cm, then the radius is 2 units and the circumference is 12.6 units while the area is 12.6 square units - the same numeric value.
How do you Find the area of a circle so that its area and circumference have the same value?
If its diameter is 4 units in length then:- Area of circle: pi*2^2 = 4*pi square units Circumference of circle: 4*pi units
What is the area and circumference of 18.4 feet?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
Why the value of pi is constant?
The value of pi is constant. It is calculated by dividing the circumference of a circle by its diameter. As the circle's circumference grows, the diameter grows at the same rate, proportionally. This means that the circumference divided by the diameter (if measured precisely) will always yield pi. If it does not, it is not a perfect circle. The ratio between the circumference and the diameter of a circle will always stay the same, no matter how you change the size of the circle.
Is the circumference and area the same thing?
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
What is the radius of a circle that has a circumference with the same numerical value as its area?
1
Can a circle's area also be it's circumference?
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.
Is the Area of a circle and circumference of a circle have the same thing?
No,Circumference is like the perimiter and Area is the whole circle.
Is the circumference and area of a circle the same?
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.
Is the area and circumference of a circle the same?
No
What is area and circumference and are they the same thing?
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.)
If the area of a circle and its circumference have the same numerical value what is the length of the radius?
Area = pi*r2 = 2*pi*r = circumference then r2 = 2r so that r = 2
Can a circumference of a circle be the same as the area of the circle?
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.

Is the area of a circle and the circumference of the circle the same?
No, the two are quite different things.
