Using 3.14 as Pi the area of circle is: 0

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!

Because of the radius of the circle

circumference = 2*pi*radius or pi*diameter

Pi is the number you get after finding the ratio of a circle's radius to its circumference. It's used in formulas to find the circumference and area of circles. The number goes on infinitely, but most people abbreviate the decimal to 3.14.

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

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.

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

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!

Because of the radius of the circle

circumference = 2*pi*radius or pi*diameter

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.

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

area=pi * r2 so divide the area by pi and take the sqrt to find the radius then circumference= 2 * pi * r
