It depends on what you want to convert the area of the circle into.

By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2

To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi

Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared

We know that the area of a circle is pi * r2. We also know that the circumference of a circle is pi * d. Therefore, when you know the circumference of a circle and want to know the area, divide the circumference by pi to give you the diameter of the circle, divide the diameter by 2 to give you the radius, square the radius and then multiply by pi to get the area. So, 10/pi = 3.183. 3.183/2 = 1.5915. 1.59152 = 2.533 2.533 * pi = 7.958 to 3 decimal places. The area of your circle is therefore 7.958cm2.

There's no such thing as the "area of a circumference", no matter how you spell it.A circumference is a length, representing the distance around a circle, and doesn'thave an area.If you know the circumference of a circle, and you call it 'C', then the area of the circle isC2 / (4 pi)

If you know the area, you can find the radius --> A = (pi) * r^2 If you have the radius, you can find the circumference --> C = (pi) * 2 * r

radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi

If you have the circumference- You have to divide the circumference by 2*Pi If you know the diameter the radius is simply half the diameter. If you know the area of a circle, the radius can be found using the formula : R = √A/π where: A is the area of the circle and π is Pi, approximately 3.142.

The circumference of a circle is the length of the circle's perimeter.

If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)

To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.
