radius=1/2 circumference
Oops! Not true. The radius equals 1/2 the diameter of a circle, and the diameter equals the circumference divided by Pi (3.14...). But none of this answers the question, so:
Any segment of the circumference of a circle is called an "arc" and the size of the arc is usually expressed in degrees.
A 900 arc, for instance, would go 1/4 of the way around the circle, since a full circle is always 3600. Halfway round would be 900, 1/3 of the way 1200, and so on.

Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
Why is half the diameter the radius?
A radius is a straight line from the circumference (boundary) of a circle to the centre. A diameter is a straight line that goes from the circumference to the centre and then continues until it reaches the circumference of the other side. In a circle, all points on the circumference are the same distance from the centre. As a result, the second part of the diameter is the same as the first. In other words, diameter = radius + radius = 2*radius.
