Circle Plot: Enter the radius and value of x. Click on Solve Y button to return y and angle in degrees.
Circle Data Conversions: Select the known circle data from the menu, enter the value, and click on a button to convert.
Angle Unit Conversions: Select the current angular unit from the menu, enter the value, and click on a button to convert. Enter a value for the radius to convert an angle to an arc length.
Angle Conversion Factors:
π radians = 180° = 200 grads
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.
