That means that a given circle doesn't have two or three diameters. For a given circle, there is a unique measurement, called its "diameter". It is the distance from one end to the other, passing through the center. Since the circle is defined as all the points that are at the same distance from a point (the center), all radii are the same distance; and the diameter is simply twice the radius.

The center of a circle lies on what?
Every diameter of the circle.
Is every chord of a circle also a diameter?
No. The chord is a diameter only if it passes through the center of the circle. In that case,it's also the longest that any chord can possibly be in that circle.
How many degrees in a circle with a diameter of 5cm?
360. There are 360 degrees in every triangle.
What is the semi major axis of a circle of diameter 24 cm?
Well, when an ellipse has zero eccentricity and is called a circle, its major and minoraxes are both the same length. In fact, every axis through the center has the samelength, even the oblique ones, and every one of them is called a "diameter".So the semi-major axis of a circle is half of the diameter, typically referred to as the "radius".In your circle, that's 12 cm.
What is half of a diameter of a circle?
The radius is half of the diameter of a circle.
The center of a circle lies on what?
Every diameter of the circle.
What does circumference and diameter of every circle?
The circumference divided by its diameter for any circle is equals pi.
Is every diameter of a circle is a secant of the circle?
If one is, they all are!
What is the circumference of a 30 inch diameter circle?
The circumference of every circle is (pi) x (diameter).The circumference of this particular circle is 30 pi.
What does pi find?
Pi is the circumference of the circle divided by the diameter of the circle. Every circle, that ever was, is, or ever will be.
How do you find the circumference of a circle when the diameter is 6.8?
To find the circumference of a circle when the diameter is given, you can use the formula C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter of the circle. In this case, the diameter is 6.8, so you would plug that into the formula: C = π(6.8) ≈ 21.41. Therefore, the circumference of the circle is approximately 21.41 units.
Why you are using pi to calculate circumference of the circle?
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
How many lines of symmetry in a circle?
That number is infinite. Every diameter of a circle is a line of symmetry.
What is the part of a circle that lies in the middle and is the same distance away from every part of the circle?
diameter?
A chord of a circle that contains the center of a circle-?
The cord of a circle that contains the center of that circle is a diameter of that circle.
Is every chord of a circle also a diameter?
No. The chord is a diameter only if it passes through the center of the circle. In that case,it's also the longest that any chord can possibly be in that circle.
How do you diameter of a circle?
You do a diameter circle!!
