USER’S GUIDE — 7Circular/Arc Function KeysThe circle key helps you quickly solve circular area, volume or arcproblems.CCircle — Displays and calculates the following val-ues, given an entered circle diameter* or radius:• Diameter (DIA)• Circle area (AREA)• Circumference (CIRC)*To enter a diameter (e.g., 10 Feet), press 1 0 f C.Ç aRadius — Enters or calculates thecircle radius(e.g., 5 f Ç a).aArc Length or Degree of Arc — A multi-functionkey that enters or calculatesArc Length orDegreeof Arc, and further solves for additional circular/arcvalues, including arched segment walls (based onthe stored On-center spacing), listed below.Press Result1 Arc Length or Degree of Arc (ARC)2 Chord Length (CORD)3 Segment Area (SEG)4 Pie Slice Area (PIE)5 Segment Rise (RISE)6 Stored On-Center Spacing (OC)7 Length of Arched Wall 1* (AW 1)* The calculator will calculate arched segment wall lengths (ifapplicable) with consecutive presses of the akey until it reach-es the last wall length.RRun (Chord Length) — Enters or calculates theChord Length. Used in conjunction with an enteredsegment rise to solve for the radius of a circle orwith an entered radius to solve for the segment rise.rRise (Segment Rise) — Enters or calculates thesegment rise. Used in conjunction with an enteredChord Length to solve for the radius of a circle orwith an entered radius to solve for the Chord Length.
