to find the circumference of a circle, which is the distance in the outside of the circle you need to use the following formula: C=dx 3.14 or circumference equals diameter times pi. The diamater is the length of the circle from end to end. Not very difficult.
A semi-circle is a 180 degree half circle. A semi-circle does not have any corners. A circle does not have corners either. There are points of beginning and end in a semi-circle. In a circle the point of beginning is the same as the ending point.
No. The Diameter is the length from one end to the next. The radius is half of that.
it's what you call circle
at the end of the circle.
A segment with end points on a circle is a chord.

An Chord is a segment with end points on the circle. Your welcome. :)
A circle as such does not have a start point nor an end point. We do however have to start at one point and end at the same point when we draw a perfect circle, but after it is drawn, the actual circle does not have a start nor an end. We might be able to see where we started and ended but this is of no significance to the actual start/end point of the circle as the circle itself does not have any.
The center of a circle is called the origin. It is a point at one end of a radius, the other end of which defines the circumference of the circle.

A segment with end points on a circle is a chord of that circle.
