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

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?

If a circles radius is 2.5cm what is the diameter?
The diameter of a circle is twice the radius.
What is the converse of If two circles have the same diameter then they have the same circumference?
The converse of the statement "If two circles have the same diameter, then they have the same circumference" is "If two circles have the same circumference, then they have the same diameter." This means that if you know two circles share identical circumferences, you can conclude that their diameters are also equal.
Is the diameter of a circle always the same?
Every diameter of the same circle is the same length, and unless someone comes alongand stretches the circle when you're not looking, the diameter doesn't change.So...YES-----------I disagree...No they are not... all circles would be the same size if that were the case.What remains a constant is that all circles are 360 degrees.==================================The question doesn't ask about " ... the diameter of circles ... ".It asks about " ... the diameter of a circle ... ".The diameter of circles is not always the same, butthe diameter of any one circle is always the same.P.S.: This is not the place to debate the answer.The "discussion area" is.
