Inradius of N-gon Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inradius of N-gon = Edge Length of N-gon/(2*tan(pi/Number of Sides of N-gon))
r_i = l_e/(2*tan(pi/N_Sides))
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Inradius of N-gon - (Measured in Meter) - Inradius of N-gon is defined as the radius of the circle which is inscribed inside the N-gon.
Edge Length of N-gon - (Measured in Meter) - Edge Length of N-gon is the length of the line segment joining two adjacent vertices of N-gon.
Number of Sides of N-gon - Number of Sides of N-gon is the number of line segments required to make a N-gon.

STEP 1: Convert Input(s) to Base Unit

Edge Length of N-gon: 10 Meter --> 10 Meter No Conversion Required
Number of Sides of N-gon: 8 --> No Conversion Required

STEP 2: Evaluate Formula

What is N-gon?

N-gon is a polygon with N sides and N vertices. An n-gon, can be either convex or concave. A convex polygon has none of its interior angles greater than 180°. On the contrary, a concave polygon has one or more of its interior angles greater than 180°. A polygon is called regular when its sides are equal and also its interior angles are equal.
