Inradius of Nonagon given Area Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inradius of Nonagon = sqrt(Area of Nonagon/(9*tan(pi/9)))
r_i = sqrt(A/(9*tan(pi/9)))
This formula uses 1 Constants, 2 Functions, 2 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
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 Nonagon - (Measured in Meter) - Inradius of Nonagon is defined as the radius of the circle which is inscribed inside the Nonagon.
Area of Nonagon - (Measured in Square Meter) - The Area of Nonagon is the amount of two-dimensional space taken up by the Nonagon.

STEP 1: Convert Input(s) to Base Unit

Area of Nonagon: 395 Square Meter --> 395 Square Meter No Conversion Required
