Radius is 1/2 of the diameter.
how to find end points of a diameter for (3,-4) and (7,2)
Two lines tangent to a circle at the endpoints of its diameter are parallel. See related link for proof.
This distance is called the diameter.
it is the diameter
It is a semicircular arc.

The points where a diameter intersects the circle are its endpoints.
An arc is a part of a circle that is defined by its endpoints. It is a segment of the circumference of the circle.

In geometry, an arc is a curved portion of a circle. It is defined by two endpoints and the points along the circumference of the circle that lie between the endpoints. The measure of an arc is typically given in degrees.
Some segments with both endpoints on a circle are not diameters.
