Inradius of Decagon Calculator

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.
Side of Decagon - (Measured in Meter) - Side of Decagon is defined as a line connecting two adjacent vertices of the Decagon.

STEP 1: Convert Input(s) to Base Unit

Side of Decagon: 10 Meter --> 10 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

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

Evaluating ... ...

r_i = 15.3884176858763

STEP 3: Convert Result to Output's Unit

15.3884176858763 Meter --> No Conversion Required

FINAL ANSWER

15.3884176858763 ≈ 15.38842 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.
