A mathematical arc is any segment of the circumference of a circle. It is normally expressed in degrees, referring to the angle between the two lines drawn from either end of the arc to the center of the circle. Therefore, a 900 arc is 1/4 of the circle's circumference and a 1800 arc is half the circumference.

the fraction of the circle covered by the arc

A piece of the circumference of a circle is called an arc A piece of the area of a circle bounded by an arc and two radii is called A sector. A piece of the area of a circle bounded by an arc and a chord is called a segment

The angle measure is: 90.01 degrees

To find the arc length, you also need to know the radius (or diameter) of the arc. The arc length is then found by finding the circumference of the full circle (2xPIxradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
