Polygon, Finding Angles Based on Entered Radius and
Number of Sides
You’re going to pour a polygon-shaped patio. Find the polygon val-
ues if the radius is 15 feet and the number of sides is 6.
KEYSTROKE DISPLAY
1. Enter radius and number of sides* to calculate the full angle:
o o 0.
1 5 f Ç a RAD 15 FEET 0 INCH
6 Ç R FULL 120.00*
2. Then calculate the bi-sect angle, side length, perimeter, and
polygon area:
R HALF 60.00*
R SIDE 15 FEET 0 INCH
R PER 90 FEET 0 INCH
R AREA 584.5671 SQ FEET
*Note: You must enter more than 3 sides for a multi-sided polygon figure or the calcu-
lator will display “None.”
