The Outer Circle Radius of Annulus is the radius of the larger circle in a pair of concentric circles that form the boundary of an annulus. It represents the distance from the center to the outer edge of the annular shape.
The calculator uses the formula:
Where:
Explanation: The outer radius is simply the sum of the inner radius and the breadth (width) of the annulus, representing the total distance from the center to the outer boundary.
Details: Calculating the outer radius is essential for determining the complete dimensions of an annulus, which is crucial in various engineering, architectural, and geometric applications where annular shapes are used.
Tips: Enter the breadth of the annulus and the inner circle radius in meters. Both values must be non-negative numbers. The calculator will compute the outer circle radius.
Q1: What is an annulus?
A: An annulus is a ring-shaped object formed by two concentric circles - the region between two circles with the same center but different radii.
Q2: Can the breadth of annulus be zero?
A: No, if the breadth is zero, the two circles would coincide and there would be no annular region. The breadth must be a positive value.
Q3: What units should I use for the inputs?
A: The calculator uses meters as the default unit, but you can use any consistent unit of length as long as both inputs use the same unit.
Q4: How accurate is this calculation?
A: The calculation is mathematically exact. The accuracy depends on the precision of your input values.
Q5: Can this formula be used for other geometric shapes?
A: This specific formula applies only to annular shapes formed by two concentric circles. Different formulas are needed for other geometric configurations.
