The circumference of a circle is 2 pi r, where r is the radius, or it is pi d, where d is the diameter.there is no circuference of pi. Circumference refers to the outer edges of circles
diameter = pi x circumference (pi = 3.1416 approximately) To find circumference, multiply diameter by pi. To find diameter, divide circumference by pi.
Diameter = Circumference/pi
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
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
Circumference of any circle = 2*pi*radius or pi*diameter
The circumference of a circle = pi*diametre = 2pi*radius
circumference = 2*pi*radius or pi*diameter
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!
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.
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
Because of the radius of the circle
Pi (3.141...) is used for circles, and circles only. You use it to find the area and circumfrence.
The Greek word for perimeter begins with the letter pi, and since circumference and perimeter are the same the letter Pi was used.
They are all related to circles Circumference = pi * diameter = 2 * pi * radius
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.
Divide by pi and then divide by 2
