The circumradius of a hendecagon (11-sided polygon) is the radius of a circle that passes through all vertices of the hendecagon. It represents the distance from the center of the hendecagon to any of its vertices.
The calculator uses the formula:
Where:
Explanation: The formula calculates the circumradius based on the side length and the sine of the central angle (π/11 radians) of the hendecagon.
Details: Calculating the circumradius is important in geometry, architecture, and engineering for designing and analyzing regular hendecagonal structures and patterns.
Tips: Enter the side length of the hendecagon in meters. The value must be positive and valid.
                    Q1: What is a hendecagon?
                    A: A hendecagon is a polygon with 11 sides and 11 angles. It is also known as an undecagon.
                
                    Q2: How is this formula derived?
                    A: The formula is derived from the relationship between the side length and the central angle in a regular polygon, using trigonometric functions.
                
                    Q3: Can this calculator be used for irregular hendecagons?
                    A: No, this calculator is specifically designed for regular hendecagons where all sides and angles are equal.
                
                    Q4: What are practical applications of hendecagon calculations?
                    A: Hendecagons are used in architectural design, coin design, and various geometric patterns in art and engineering.
                
                    Q5: How accurate is this calculation?
                    A: The calculation is mathematically exact for a perfect regular hendecagon, though real-world measurements may have practical limitations.
