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

To calculate the volume of an arc, you first need to determine the shape of the arc (e.g., it could be a sector of a circle). Once you know the shape, use the appropriate formula for calculating the volume of that shape, such as the volume of a sector of a circle or a segment of a sphere. Calculate the volume based on the given measurements of the arc.

If it is a sector of a circle then the arc is the curved part of the circle which forms a boundary of the sector.

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.
