- Enter the Outer Radius (cm).
- Enter the Inner Radius (cm).
- Click on the Calculate button to get the Area (cm²).
How the Annulus Area Calculator Works
Area = pi*(outer_radius^2-inner_radius^2)The area of an annulus is calculated using the formula area = pi * (outer_radius^2 - inner_radius^2). This means you square both the outer radius and inner radius, subtract the inner from the outer, and then multiply by pi. For example, if the outer radius is 5 cm and the inner radius is 3 cm, the area would be pi * (5^2 - 3^2) = pi * (25 - 9) = pi * 16, which is approximately 50.27 cm².
