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.

the formula for the arc of a triangle is the arc length is equal to the angle times the radius. s=arc length theta=angle made y length of the arc lenth r=radius s=theta times radius
How to find the area of a fillet. Is it area =0.2146 radius squared
The length of an arc is the radius times the angle in radians that the arc subtends length = radius times angle in degrees times pi/180
When the arc length is the same size as a circle's radius it is known as a radian and it measures just under 57.3 degrees
the general formula is arc length is equal the radius times the angle. s=r< s=arc length r=radius <=angle
