Inradius of Octagon given Perimeter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inradius of Octagon = (1+sqrt(2))*Perimeter of Octagon/16
r_i = (1+sqrt(2))*P/16
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 Octagon - (Measured in Meter) - The Inradius of Octagon is the radius of incircle of the Regular Octagon or the circle that contained by the Octagon with all edges touch the circle.
Perimeter of Octagon - (Measured in Meter) - The Perimeter of Octagon is the total length of all the boundary lines of the Regular Octagon.

STEP 1: Convert Input(s) to Base Unit

Perimeter of Octagon: 80 Meter --> 80 Meter No Conversion Required

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° and each exterior angle will be 45°.
