the fraction of the circle covered by the arc
The length of the major arc is r*x where r is the radius of the circle and x is the larger of the angles, measured in radians, formed at the centre by the radii from the two ends of the arc. If you measure angles in degrees, the length is r*x*pi/180.
length=n/360*2*pi*radius
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).

To find major arcs in a circle, first identify the endpoints of the arc on the circumference. Measure the angle subtended by the endpoints at the center of the circle; if the angle is greater than 180 degrees, the arc is a major arc. Alternatively, you can calculate the minor arc (the shorter arc between the two points) and subtract its length from the total circumference to find the length of the major arc. Major arcs are typically labeled with three points, including the endpoints and a point on the arc itself.
Since the minor arc is 30 degrees, the major arc is 330 degrees (360 - 30). So we have: 330 degrees : arc length 10 30 degrees : arc length x 330/30 = 10/x 11/1 = 10/x x = 10/11 x = 0.9 approximately So the length of the minor arc is approximately 0.9 units.
It is: 72-lenghth of major arc = length of minor arc

If you have only the arc length then you cannot find the diameter.
To find the arc length using radians, you can use the formula: Arc Length Radius x Angle in Radians. Simply multiply the radius of the circle by the angle in radians to calculate the arc length.
The length of the arc is r*theta where r is the radius and theta the angle subtended by the arc at the centre of the circle. If you do not know theta (or cannot derive it), you cannot find the length of the arc.
length of arc/length of circumference = angle at centre/360 Rearranging the equation gives: length of arc = (angle at centre*length of circumference)/360
Find the circumference of the whole circle and then multiply that length by 95/360.
