The Outer Radius of Circular Ring formula calculates the radius of the outer boundary of a circular ring when you know the inner radius and the width of the ring. A circular ring is the area between two concentric circles.
The calculator uses the formula:
Where:
Explanation: The outer radius is simply the sum of the inner radius and the width of the ring. This formula works because the width represents the radial distance between the inner and outer circles.
Details: Calculating the outer radius is essential in various engineering and design applications involving circular rings, such as pipe design, mechanical components, architectural elements, and manufacturing processes where precise dimensions are critical.
Tips: Enter the width of the circular ring and the inner radius in meters. Both values must be non-negative numbers. The calculator will compute the outer radius by adding these two values together.
Q1: What is a circular ring?
A: A circular ring is the region between two concentric circles - it has an inner circle and an outer circle sharing the same center point.
Q2: Can this formula be used for non-circular rings?
A: No, this specific formula only applies to circular rings where both inner and outer boundaries are perfect circles with a common center.
Q3: What units should I use for the inputs?
A: The calculator uses meters, but you can use any consistent unit of length as long as both inputs are in the same units.
Q4: What if the width is zero?
A: If width is zero, the outer radius equals the inner radius, meaning there is no ring - you just have a single circle.
Q5: How is this different from calculating diameter?
A: This calculates radius, not diameter. To get outer diameter, you would multiply the calculated outer radius by 2.
