How to Define the width across a circle?
diameter
How do you define radian?
An informal definition: If you take a radius of a circle and wrap it around its circumference then the angle which that arc will make at the centre of the circle is 1 radian.More formally, a radian is 1/(2*pi) of a whole angle.

WHAT ARE THE VERTICES OF A CIRCLE?
Depending on how you want to define vertices, a circle either has no vertices or the circle is composed of infinite vertices. A vertex is where two straight edges meet. Since a circle is continuously curved you can easily argue that it has no straight edges to meet and form a vertex. From a limits standpoint though it has infinitely many straight segments - but they are are all of length 1/∞
Do concentric circles have the same circles?
No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.
How do you define half circle?
A semi-circle
Define what the circumference of a circle?
The circumference of a circle is the distance around it.
Define the center of a circle?
The center of a circle is the point from which all points on the circle are equidistant.

How to Define the width across a circle?
diameter
Standard equation of a circle with 2 points?
Two points do not provide enough information to define a circle: a minimum of three points is required to uniquely define a circle unless one of the points happens to be the centre and the other is on the circle. In that case, however, it is necessary to know which is which.
Pi is a mathematical constant related to circle define Pi?
Ratio of the perimeter of a circle (circumference) to its diameter
What is mathematical phrase for a circle?
You can define a circle as the locus (set) of all points equidistant from a given point.
Define the diameter of a circle?
a straight line passing from side to side through the center
Is it true that a circle is determined if a given segment is its diameter?
Yes. The center is the mid-point of the segment, and that's all you need to uniquely define a circle.
When revising your essay you should circle terms your audience may be unfamiliar with in order to?

What is a center coordinate of 2 points known circle?
Knowing two points on a circle does not define a unique circle, so it is impossible to find the centre of the circle as there are infinitely many centres possible.
