The answer depends on what information you do have: radius, arc length, central angle etc.

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.
In a unit circle, the arc length ( s ) is directly equal to the angle ( \theta ) in radians. Therefore, if the arc length of a sector is 3 radians, the measure of the angle of the sector is also 3 radians.

sector
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
In a unit circle, the arc length ( s ) is directly equal to the angle ( \theta ) in radians. Therefore, if the arc length of a sector is 3 radians, the measure of the angle of the sector is also 3 radians.
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.
