16 — CONSTRUCTION MASTER PROCircular Function KeysThe circle key helps you quickly solve circular area, volume or arcproblems.[Circ] — CircleDisplays and calculates the following values, given an entered circlediameter* or radius:• diameter• circle area• circumference*To enter a diameter (e.g., 10 feet), press 10 [Feet] [Circ].[Conv] [Diag] — RadiusEnters or calculates the circle radius (e.g., 5 [Feet] [Conv] [Diag]).[Conv] [Circ] — Arc Length or Degree of ArcEnters or calculates arc length or degree of arc, and further solves foradditional circular values, listed below.If a circle diameter and arc degree (or arc length) are entered, furtherpresses of [Circ] will display and calculate the following:• arc length or degree of arc• chord length• segment rise• pie slice area• segment area (between the chord and the arc)[Run] — Run (Chord Length)Used with [Rise] or [Conv] [Diag] to find the chord length or the ra-dius of a circular segment. If the segment rise and radius have beenentered, this key will display the chord length of the circular seg-ment.
