Circular Function Keys
The circle key helps you quickly solve circular area, volume or arc
problems.
[Circ] — Circle
Displays and calculates the following values, given an entered circle
diameter* or radius:
•
diameter
•
circle area
•
circumference
*To enter a diameter (e.g., 10 feet), press 10 [Feet] [Circ].
[Conv] [Diag] — Radius
Enters or calculates the circle radius (e.g., 5
[Feet] [Conv] [Diag]).
[Conv] [Circ] — Arc Length or Degree of Arc
Enters or calculates arc length or degree of arc, and further solves for
additional circular values, listed below.
If a circle diameter and arc degree (or arc length) are entered, further
presses 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 been
entered, this key will display the chord length of the circular seg-
ment.
