Apothem of Regular Polygon Calculator
Result
Apothem of Regular Polygon Calculator The Apothem of Regular Polygon Calculator finds the apothem — the distance from the center to the midpoint of a side — of a regular polygon, then uses it to compute the perimeter and area. The formula used is: Apothem — free online calculator.
Formula
- Apothem of Regular Polygon Calculator calculates its result from S, Periods. It uses the formula Apothem = s / (2×tan(π/n)); Area = (perimeter × apothem) / 2 = (n×s×apothem)/2. Change any input to recalculate the result instantly.
- The main inputs are S, Periods. Enter them in the units and format shown in the calculator.
