An arc is a portion of the circumference of a circle, defined by two endpoints on the circle. In contrast, a sector is a region enclosed by two radii and the arc connecting them, resembling a "slice" of the circle. Essentially, while an arc is just the curved line, a sector includes the area bounded by the arc and the radii.
What else can I help you with?
How do you find the arc in a sector?
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.

How to find a sector area in a circle if you have only the arc length?
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.
How do you work out the area of a sector when given the length of the arc?
If you're only given the length of the arc, then you can't. You also need to know the fraction of the circle that's in the sector. You can figure that out if you know the angle of the arc, or the radius or diameter of the circle. -- Diameter of the circle = 2 x (radius of the circle) -- Circumference of the circle = (pi) x (Diameter of the circle) -- (length of the arc)/(circumference of the circle) = the fraction of the whole circle that's in the sector or -- (degrees in the arc)/360 = the fraction of the whole circle that's in the sector -- Area of the circle = (pi) x (radius of the circle)2 -- Area of the sector = (Area of the circle) x (fraction of the whole circle that's in the sector)
What is a pie shaped portion of a circle called?
A pie-shaped portion of a circle is called a "sector." A sector is defined by two radii and the arc between them, representing a fraction of the circle's area. The angle at the center of the circle determines the size of the sector.

What is the relation between area of a sector and length of an arc of a circle?
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 to find a sector area in a circle if you have only the arc length?
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.

The part of a circle enclosed by to radii and an arc?
Is a SECTOR. or SEGMENT.
What is a region bounded by an ark of a circle and radii to the endpoints of the arc?
The region bounded by an arc of a circle and the radii to its endpoints is known as a sector. A sector resembles a "slice" of the circle and is defined by the two radii extending from the center of the circle to the endpoints of the arc. The area of this sector can be calculated based on the central angle and the radius of the circle.
Is A of a circle is a region bounded by an arc of a circle and radii to the end points of the arc?

What is sector?
a sector is a portion of a circle bounded by the two radii and the included arc.
