Calculating the area between two intersecting circles can be essential in various applications, including geometry, engineering, and design. This area is bounded by the intersection points of the circles and is calculated using a specific formula that considers the radii of the circles and the distance between their centers. Our calculator simplifies this process, allowing you to obtain the area with just a few inputs.

**Formula**

The area (A) between two intersecting circles is calculated using the formula:

A = r1² * cos⁻¹((d² + r1² – r2²) / (2 * d * r1)) + r2² * cos⁻¹((d² + r2² – r1²) / (2 * d * r2)) – 0.5 * √((d + r1 + r2) * (d + r1 – r2) * (d – r1 + r2) * (d – r1 – r2))

where r1 and r2 are the radii of the two circles, and d is the distance between their centers.

**How to Use**

- Enter the radius of the first circle in the “Radius of First Circle” field.
- Enter the radius of the second circle in the “Radius of Second Circle” field.
- Enter the distance between the centers of the two circles in the “Distance Between Centers” field.
- Click the “Calculate” button to get the area between the intersecting circles.

**Example**

If the radius of the first circle is 5 units, the radius of the second circle is 7 units, and the distance between the centers is 6 units, entering these values into the calculator will provide you with the area between the two intersecting circles.
