For a circle:
Arc Length= R*((2*P*A)/(360))
R being radius, P being pi (3.14159), and A being the measure of the central angle.

No, in order to fine the arc length you need a formula which is: Circumference x arc measure/360 degrees
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
Arc length = [2*Pi*(Radius of Pizza)]/(number of slices in a pizza)
There is none since an angle does not have a length.
you need to know the formula the arc length is equal to the radius times the angle made by the length of arc s = r(theta) s=arc length r=radius theta=angle
