Radius — Enters or calculates the circle radius
(e.g., 5 f Ç a).
Arc Length or Degree of Arc — A multi-function
key that enters or calculates arc length or degree of
arc , and further solves for additional circular/arc val-
ues, including arched rake-walls (based on the
stored on-center spacing), listed below.
If a circle diameter is entered into the C key and
arc degree (or arc length) entered into the a key,
further presses of a will display and calculate the
following:
Press Result
1 Arc Length or Degree of Arc
2 Chord Length
3 Segment Area
4 Pie Slice Area
5 Segment Rise
6 Stored On-Center Spacing
7 Length of Arched Wall 1
8 Length of Arched Wall 2
9 Length of Arched Wall 3 (if applicable), etc.*
*Note: The calculator will calculate arched rake-wall stud sizes
with consecutive presses of the a key until it reaches the last
stud.
Run (Chord Length) — Enters or calculates the
chord length . Used in conjunction with an entered
segment rise to solve for the radius of a circle or
with an entered radius to solve for the segment rise.
Rise (Segment Rise) — Enters or calculates the
segment rise . Used in conjunction with an entered
chord length to solve for the radius of a circle or with
an entered radius to solve for the chord length.
