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
Diagonal across Three Sides of Decagon - (Measured in Meter) - Diagonal across Three Sides of Decagon is a straight line joining two non-adjacent sides which is across three sides of the Decagon.
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.
STEP 1: Convert Input(s) to Base Unit
Inradius of Decagon: 15 Meter --> 15 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
d3 = sqrt(14+(6*sqrt(5)))/2*(2*ri)/sqrt(5+(2*sqrt(5))) --> sqrt(14+(6*sqrt(5)))/2*(2*15)/sqrt(5+(2*sqrt(5)))
Evaluating ... ...
d3 = 25.5195242505612
STEP 3: Convert Result to Output's Unit
25.5195242505612 Meter --> No Conversion Required
25.5195242505612 25.51952 Meter <-- Diagonal across Three Sides 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.
