It is the distance across the entire span of the circle.
Draw a line from one side to the next side like a cord, except directly through the center so that the circle is split in 2 identical semi-circles. The length of this line is the diameter.
The radius of the circle is HALF the diameter so you have the relationships:
D = R/2
or
R = 2D
for R = the radius and D = the diameter

How do you find the diameter of water?
Only circles (or spheres) have a diameter
If a circles radius is 2.5cm what is the diameter?
The diameter of a circle is twice the radius.
How long is a penny?
Circles have a diameter, not length. The diameter of a US cent is 19 mm.
Is the radius of a circle half of the circles diameter?
Yes, the radius is half the diameter. (Eg, if the DIAMETER is 6, the RADIUS would be 3).
How do you find the diameter of a rectangel?
Circles have diameters, rectangles have diagonals.
Does a rectangle have diameter?
NO!!! Diameter refer to circles. A rectamgle has a DIAGONAL.
How do you find the diameter of water?

What is the circles diameter if the circumference is 12.56?
diameter = 12.56/pi
If a circles radius is 2.5cm what is the diameter?
The diameter of a circle is twice the radius.
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.
What is the circles diameter if the circumference is 31.4?
It is: diameter = 31.4/pi which is about 10 units
How long is a penny?
Circles have a diameter, not length. The diameter of a US cent is 19 mm.
Radius is 3 cm what is diameter?
Since with circles the radius is half the diameter, the diameter would be 6 cm.
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.
Where is the width and diameter of a rectangle?
A rectangle is an elongated square. It doesn't have a diameter; only circles have diameters.
What is the ratio to any circles circumference to the diameter?
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
