Circular Sector and Segment Calculator:
Select the sector angle or arc length from the menu and enter the value.
Enter the circle radius.
Arc:
Portion of the circle circumference. Defined in angular units or length.
Chord:
The line segment connecting the endpoints of an arc.
Center to Chord:
Distance from the center of the circle to the midpoint of the chord.
Sagitta:
Balance of the distance defined above, from the midpoint of the chord to the arc.
Center to Chord + Sagitta = Radius
Sector Area:
The area of the circle bounded by two radii and an arc.
Section Area:
The area of the circle bounded by the chord and the arc.
