Inradius of Decagon given Diagonal across Two Sides Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inradius of Decagon = sqrt(5+(2*sqrt(5)))/2*(2*Diagonal across Two Sides of Decagon)/sqrt(10+(2*sqrt(5)))
r_i = sqrt(5+(2*sqrt(5)))/2*(2*d₂)/sqrt(10+(2*sqrt(5)))
This formula uses 1 Functions, 2 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Inradius of Decagon - (Measured in Meter) - Inradius of Decagon is the length of the straight line from the center to any point on the incircle of the Decagon.
Diagonal across Two Sides of Decagon - (Measured in Meter) - Diagonal across Two Sides of Decagon is a straight line joining two non-adjacent sides which is across two sides of the Decagon.

STEP 1: Convert Input(s) to Base Unit

Diagonal across Two Sides of Decagon: 19 Meter --> 19 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_i = sqrt(5+(2*sqrt(5)))/2*(2*d₂)/sqrt(10+(2*sqrt(5))) --> sqrt(5+(2*sqrt(5)))/2*(2*19)/sqrt(10+(2*sqrt(5)))

Evaluating ... ...

r_i = 15.371322893124

STEP 3: Convert Result to Output's Unit

15.371322893124 Meter --> No Conversion Required

FINAL ANSWER

15.371322893124 ≈ 15.37132 Meter <-- Inradius of Decagon

What is a Decagon?

Decagon is a polygon with ten sides and ten vertices. A decagon, like any other polygon, can be either convex or concave, as illustrated in the next figure. A convex decagon has none of its interior angles greater than 180°. To the contrary, a concave decagon (or polygon) has one or more of its interior angles greater than 180°. A decagon is called regular when its sides are equal and also its interior angles are equal.
