It is part of a curve. If that curve happens to be a circle, then it is a fraction of a circumference but it need not be.

First of all to correct your English grammar. Any noun, 'arc' in this case, that starts with a vowel , 'a' in this case, is preceded by the indefinite article 'an' , NOT 'a' . So the question should read 'What is an arc of a circle?' Answer: An arc is a section of the circumference , between two given points on the circumference. Arc as given above. Radius ; distance from circle centre to the circumference Diameter ; Straight line distance from the circumfewrence, through the centre to the circumference on the opposite side. Chord ; (Pronounced ; cord/kord). A straight line between any two points on the circumference, that does NOT touch the centre. Sector ; The fraction of a circles area enclosed between two radii and the corresponding arc.
A part of the circumference is called an arc. If the circumference is split into two unequal arcs then the larger portion is referred to as the major arc and the lesser portion as the minor arc.

An arc
The entire circumference has a central angle of 360 degrees. The arc is a fraction of the circumference. The fraction is (central angle) divided by (360). So the arc length is: (circumference) x (central angle) / (360) .
the fraction of the circle covered by the arc
An arc is a fraction of its circumference

Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)
Part of the circumference of a circle is called an arc.
