Circumradius of Nonagon Formula:
From: | To: |
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.
The calculator uses the formula:
Where:
Explanation: This formula calculates the circumradius of a regular nonagon based on its inradius, using trigonometric relationships specific to the 9-sided polygon.
Details: Calculating the circumradius is essential in geometry, architecture, and engineering for designing and analyzing nonagonal structures, patterns, and components.
Tips: Enter the inradius value in meters. The value must be positive and greater than zero for accurate calculation.
Q1: What is the relationship between circumradius and inradius?
A: In a regular nonagon, the circumradius is always larger than the inradius, and their ratio is constant for all regular nonagons.
Q2: Can this formula be used for irregular nonagons?
A: No, this formula applies only to regular nonagons where all sides and angles are equal.
Q3: What are practical applications of this calculation?
A: This calculation is used in architectural design, mechanical engineering, and geometric pattern creation involving nonagonal shapes.
Q4: How accurate is this calculation?
A: The calculation is mathematically exact for regular nonagons, with accuracy limited only by the precision of the input value and computational floating-point arithmetic.
Q5: What units should be used for the input?
A: The calculator uses meters as the default unit, but any consistent unit of length can be used as long as the input and output use the same unit.
