If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.

sector
Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees
It depends on what information you have: the radius and the area of the sector or the length of the arc.
The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.

It depends on what else is known about the sector: length of arc, area or some other measure.

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
how
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.
