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.

Is a circle an arc?
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
What is the relation between arc and circle?
An arc is a part of the circumference of a circle.
Is a part of a circle an arc?
Yes, a part of a circle is called an arc. An arc is defined as a segment of the circumference of a circle, measured between two points on the circle. The length of an arc can vary depending on the angle subtended at the center of the circle by those two points.
What does an arc look like in circle geometry?
An arc is just part of the circumference of a circle.
What is an arc of a circle whose endpoints are endpoints of the diameter of the circle called?
It is a semicircular arc.

What is the length of an arc of a circle?

How to find a sector area in a circle if you have only the arc length?
If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.

the fraction of the circle covered by the arc
