Circle And Arc Calculations; Circumference And Area Of A Circle; Arc Length - Degree And Diameter Known; Arc Length - Chord Length And Segment Rise Known - Calculated Industries 4065 User Manual

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)
