Perimeter of Circular Ring Calculator

Calculate Perimeter





Formula

The formula to calculate the Perimeter of a Circular Ring given its outer and inner radius is:

\[ P = 2\pi (r_{\text{Outer}} + r_{\text{Inner}}) \]

Definition

The Perimeter of a Circular Ring is the length of the ring around all the edges. The Outer Radius of a Circular Ring is the radius of the larger circle of the two concentric circles that form its boundary. The Inner Radius of a Circular Ring is the radius of its cavity and the smaller radius among the two concentric circles.

Example Calculation

Let's assume the following values:

Using the formula:

\[ P = 2\pi (10 + 6) = 2\pi \times 16 = 32\pi \approx 100.530964914873 \, \text{meters} \]

The Perimeter of the Circular Ring is approximately 100.530964914873 meters.
