SEGMENT & PORTION CALCULATIONS - USING DIAMATER AND ARC VALUE
Example: You have a circle with a 6 Foot diameter and an arc length of 4 Feet 4 Inches.
Find the arc degree, chord length, segment rise, segment and pie slice area, and segment rise.

2. Enter arc length*:
ARC 82.76˚
3. Calculate the degree of arc:

4. Calculate the chord length:
SEG 2.035873
SQ Feet
5. Calcuate the segment area:
PIE 6.5

6. Calculate the area of the “pie slice”:
RISE 0

7. Calculate the segment rise:
d= 6’
