In geometry a diameter of a circle is defined as a straight line which passes through the centre of a circle and whose end points both lie on the circle.
The length of this line can be used to find both the area and circumference of a circle.
C = pi(d)
A = pi(d)2/4
Where:
c = circumference (m)
a = area (m2)
d = diameter (m)
piA = 3.14159265
APi is is a mathematical constant whose value is the ratio of any circle's circumference to its diameter. Shown here to 8 decimal places.

Pi is the ratio of a circles circumfrance to its what?
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
Radius is 3 cm what is diameter?
Since with circles the radius is half the diameter, the diameter would be 6 cm.
Do two circles have the same circumference if they have the same diameter?
Yes.
If the diameter of a circle is 8 inches what is the circles radius?
The radius will be half the diameter of 8 inches which is 4 inches
What types of circles are there?
Radius, Diameter, Arc,Seicircle, Circumference and area.
