Most scientific calculators have a button for pi. So to find the circumference of a circle multiply pi by the diameter. If there is no pi button you can approximate pi as 3.14.
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
multiply the diameter times pi (3.14159265)
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
Diameter of a circle = circumference/pi
You multiply the circle's diameter by 3.14 (Pi) to get the circumference.
Diameter = circumference/pi
Circumference of a circle = 2*pi*radius
Diameter = circle's circumference/pi
Divide the circumference by Pi.
The formula to find the circumference of a circle is C = 2πr, 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 = πr^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 = 2πr to find the circumference.
The circumference of a circle is found using the following formula: Circumference of a Circle = Pi x r2 So with these equation in mind we get the following problem. Circumference of a Circle = 3.14 x 14 Circumference of a Circle = 43.96 units

using pi
pi times diameter
By using the equation 2πr that is used to find the circumference, you get 12.56m
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
