Why is the diameter of a circle always twice the length of the radius?
A circle is the locus of points that are equidistant from a fixed point. As a result, all radii of the circle must be of the same length. A diameter is a straight line that goes from the circumference to the centre and on to the circumference on the other side. Thus it is a radius from the circumference to the centre and then another radius from the centre to the circumference. And since these are the same, it is 2 radii in length.
A circle will have different radii but they will all be the same length?
Yes, all radii of a circle have the same length. One often thinks of the radius as being this length.
How many radiuses does a circle have?
The plural of 'radius' is 'radii', not 'radiuses'. A circle has an infinite number of radii, but they are all of the same length.
Does two radii equal one diameter?
That's right. In a circle, the length of a diameter will be the same as twice the length of a radius.
Is concentric circle and congruent circle are they same?
No. Concentric circles have the same centre but not [usually] the same radius. Congruent circles have the same radius, but not [usually] the same centre. If you have two concentric congruent circles one will be exactly on top of the other.
One radius of a circle is the same length as any other radius of the same circle?
true (apex
One radius of a circle is the same length as any other radius of any other radius?
The radius is the distance from the center of the circle to its edge. No matter how you draw this radius, it is one value of one length only, for any given circle.
What is the length of a radius and the length of a diameter?
The length of a radius of a circle is half of the diameter of the same circle. So, diameter is always twice the radius.
What is the relationship between the length of a radius of a circle and the length of a diameter of the same circle?
The radius is half the diameter.
Segment that has one endpiont at the center and the other endpoint on the circle?
A radius of a circle is a line segment joining the center of the circle to a point on the circle. All such segments have the same length, and this length also called the radius of the circle.
How does the length of a diameter of a circle compare to the length of a radius of that same circle?
It is two times greater
What is the difintion for radius?
A radius is the distance from the center of a circle, to the border. In a circle, all radii have the same length.
Is every radius in a circle the same length?
No it all depends on the size of the circle.
Can a circle be drawn with any center and any radius?
The center of a circle is the same for all circles but the length of the radius can change

A circle will have different radii but they will all be the same length?
Yes, all radii of a circle have the same length. One often thinks of the radius as being this length.
What is the ratio of the diameter of the length of its radius?
diameter to radius ratio (for same circle) is 2:1
