circumference = 2*pi*radius or pi*diameter

Because of the radius of the circle

to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!

Radius = square root of (area/pi) Circumference = 2*pi*radius

Area = (pi) x (Radius)2Radius = sqrt(area/pi)Circumference = (2 pi) x (Radius) = (2 pi) x sqrt(area/pi)Circumference = 2 x sqrt(pi x area)

Pi times the diameter of a circle gives its circumference.

Circumference of any circle = 2*pi*radius or pi*diameter

The circumference of a circle = pi*diametre = 2pi*radius

Using 3.14 as Pi the area of circle is: 0

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

If you are talking about circles determine the radius by dividing the Area by pi and take the square root of the result. Then multiply the radius by two times pi.

To calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. Then you get the circumference.

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

One definition of pi is the ratio of the circumference, C, of a circle to its diameter.,d. pi=C/d The area of a circle is (pi)r2 or (pi)d2/4 where r is the radius.
