## Diagonal of Decagon across two sides given circumradius Solution

STEP 0: Pre-Calculation Summary
Formula Used
d2 = (((2*r)/(1+sqrt(5)))/2)*sqrt(10+2*sqrt(5))
This formula uses 1 Functions, 1 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Radius - Radius is a radial line from the focus to any point of a curve. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Radius: 10 Meter --> 10 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
d2 = (((2*r)/(1+sqrt(5)))/2)*sqrt(10+2*sqrt(5)) --> (((2*10)/(1+sqrt(5)))/2)*sqrt(10+2*sqrt(5))
Evaluating ... ...
d2 = 11.7557050458495
STEP 3: Convert Result to Output's Unit
11.7557050458495 Meter --> No Conversion Required
11.7557050458495 Meter <-- Diagonal across two sides

## 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.
