By using the well-known formula, A = pi x r2, and expressing the radius in terms of the circumference, r = c / (2 x pi). Replace in the first formula, and simplify.

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.
To find the area of a circle using the circumference, you need to use the formula Area=Circumference squared divided by four times pi. For this type of equation, pi would be equal to 3.14.
The area of a circle that has a circumference of 16pi is: 201.1 units2
The area of a circle, if its circumference is 20π, is: 314.16 square units.
c/4(3.14)
You dived the area by the circumference of the circle.
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.
To express a quantity in terms of pi, you need to relate it to a circular measurement, such as the circumference or area of a circle. For example, if you have the circumference of a circle, you can use the formula ( C = 2\pi r ), where ( r ) is the radius, to express the circumference as a multiple of pi. Similarly, for the area, use ( A = \pi r^2 ) to express the area in terms of pi. Simply factor out pi from the equation to achieve the desired expression.
To find the area of a circle using the circumference, you need to use the formula Area=Circumference squared divided by four times pi. For this type of equation, pi would be equal to 3.14.
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
The area of a circle that has a circumference of 16pi is: 201.1 units2
The area of a circle, if its circumference is 20π, is: 314.16 square units.
The area of circle with a circumference of 20 is: 31.83 units squared.
If the area of a circle is 28.26 the circumference is: 18.84 units.
