CIRCLE AND ARC CALCULATIONS

Circle/Arc values can be solved by entering any two of the following

values: Arc Length/Angle, Diameter/Radius, Chord Length (Run),

and Segment Rise (Rise).

It is recommended that you clear the calculator (press o twice)

after calculating right-triangle solutions prior to beginning an Arc or

Circle solution.

Note: Circle/Arc solutions cannot be solved for the following cases:

• Entered Arc Length and Chord Length (Run)

• Entered Arc Length and Segment Rise (Rise)
