The diameter is the chord (line that goes from the circle to the circle) that goes through the center of the circle. It is the largest chord. It is also equal to twice the radius.
By dividing the circumference by 2*pi will give you the radius and twice the radius gives you the diameter.
you half the diamater to get the radius, then you square the radius. Then you times it by 3.14. Always. example. Diameter=4cm then radius =2cm squared=4cm 4x3.14=12.56
Circumference = pi x diameter 3.5 = 3.1415 x diamater diameter = 3.5/3.1415 =1.114 cm
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
A circumference of 78.54m
The circumference of a circle is the perimeter of the circle for a given diamater.
3.142
approximately 28.26 cm2
circumference = pi*4.6
113.1 square cm
The circumference of a circle with a 60-foot diameter is about 118.5 feet.
You double the radius.. if the radius is 10 the diameter is 20.
circumference = 18*pi feet
the diamater you goobers
Always
I believe if somebody talks about a "6-inch circle", then the 6 inches refers, precisely, to the diameter.
