1. What is Circumradius of Nonagon?

The Circumradius of a Nonagon is the radius of a circumcircle that touches each of the vertices of the Nonagon. It is an important geometric property used in various mathematical and engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ r_c = \frac{P}{18 \times \sin(\pi/9)} \]

Where:

Explanation: This formula calculates the circumradius based on the perimeter of a regular nonagon using trigonometric relationships.

3. Importance of Circumradius Calculation

Details: Calculating the circumradius is essential in geometry, architecture, and engineering for designing and analyzing nonagonal structures and patterns.

4. Using the Calculator

Tips: Enter the perimeter of the nonagon in meters. The value must be positive and greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a regular nonagon?
A: A regular nonagon is a nine-sided polygon with all sides equal and all interior angles equal.

Q2: How is circumradius different from inradius?
A: Circumradius is the radius of the circumscribed circle that passes through all vertices, while inradius is the radius of the inscribed circle that touches all sides.

Q3: Can this calculator be used for irregular nonagons?
A: No, this formula is specifically for regular nonagons where all sides and angles are equal.

Q4: What are practical applications of circumradius calculation?
A: Used in architectural design, mechanical engineering, and geometric pattern creation where nonagonal shapes are involved.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise for regular nonagons, with accuracy depending on the precision of the input values.
