## Area of Octagon given inradius Solution

STEP 0: Pre-Calculation Summary
Formula Used
A = 2*(((2*ri)/(1+sqrt(2)))^2)*(1+sqrt(2))
This formula uses 1 Functions, 1 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Inradius - Inradius is defined as the radius of the circle which is inscribed inside the polygon. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Inradius: 10 Meter --> 10 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
A = 2*(((2*ri)/(1+sqrt(2)))^2)*(1+sqrt(2)) --> 2*(((2*10)/(1+sqrt(2)))^2)*(1+sqrt(2))

## What is an octagon?

Octagon is a polygon in geometry, which has 8 sides and 8 angles. That means the number of vertices is 8 and the number of edges is 8. All the sides are joined with each other end-to-end to form a shape. These sides are in a straight line form; they are not curved or disjoint with each other. Each interior angle of a regular octagon is 135°

## How to Calculate Area of Octagon given inradius?

Area of Octagon given inradius calculator uses area = 2*(((2*Inradius)/(1+sqrt(2)))^2)*(1+sqrt(2)) to calculate the Area, The Area of Octagon given inradius formula is defined as measure of the total area that the surface of the object occupies of octagon, where A=2a^2/sqrt(2)-1 where a is side and A is area of octagon. Area and is denoted by A symbol.

How to calculate Area of Octagon given inradius using this online calculator? To use this online calculator for Area of Octagon given inradius, enter Inradius (ri) and hit the calculate button.
