To calculate the arc length of a sector:
calculate the circumference length, using (pi * diameter), then multiply by (sector angle / 360 degrees)
so : (pi * diameter) * (sector angle / 360) = arc length

if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
sector
There is no direct relation between the area of a sector and the length of an arc. You must know the radius (or diameter) or the angle of the sector at the centre.
how
If a sector has an angle of 118.7 and an arc length of 58.95 mm its radius is: 28.45 mm
