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.
You will have to measure some part of the circle. As long as you have absolutely no information about a circle, you can't do any calculations.
Divide the circumference by the value of Pi - that will give you the diameter.
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.

The circumference is: 32.1
Divide the circumference by the value of Pi - that will give you the diameter.
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
The formula to find the circumference of a circle is C = 2ฯr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = ฯr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2ฯr to find the circumference.

To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ).
