a straight line passing from side to side through the center
A semi-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.
In order to fully understand what the radius of a given circle is, you must know the diameter. The diameter is the distance across the circle through the center. The radius of a circle is half the diameter. For example, if the diameter of a circle is 8 inches, then the radius would be 4 inches.
No it's made by the circle that how they get the circle not the center.

Yes. The center is the mid-point of the segment, and that's all you need to uniquely define a circle.
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.

A RADIUS connects the center of a circle to any point on the circle.
A chord of a circle that contains the center of the circle is called the diameter.
The line from the center of a circle to a point on the circle is the radius.
The point from which the circle is drawn IS the center.
The radius is the distance between the center of a circle and a point on the circle
