## Angle of intersection between two Circles Solution

STEP 0: Pre-Calculation Summary
Formula Used
∠A = arccos((((r1)^2)+((r2)^2)-((DBetweenCenters)^2))/(2*r1*r2))
This formula uses 2 Functions, 3 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
arccos - Inverse trigonometric cosine function, arccos(Number)
Variables Used
Radius 1 - Radius 1 is a radial line from the focus to any point of a curve. (Measured in Meter)
Radius 2 - Radius 2 is a radial line from the focus to any point of a curve. (Measured in Meter)
Distance between centers - Distance between centers is the distance between two centers of circle. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Radius 1: 11 Meter --> 11 Meter No Conversion Required
Radius 2: 13 Meter --> 13 Meter No Conversion Required
Distance between centers: 10 Meter --> 10 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
∠A = arccos((((r1)^2)+((r2)^2)-((DBetweenCenters)^2))/(2*r1*r2)) --> arccos((((11)^2)+((13)^2)-((10)^2))/(2*11*13))
Evaluating ... ...

## What is a circle

A circle is a round shaped figure that has no corners or edges. The center of a circle is the center point in a circle from which all the distances to the points on the circle are equal. This distance is called the radius of the circle. Segment of a Circle, A segment is a region bounded by a chord of a circle and the intercepted arc of the circle. A segment with an intercepted arc less than a semicircle is called a minor segment. A sector with an intercepted arc greater than a semi-circle is called a major segment.

### FAQ

What is Angle of intersection between two Circles?
The Angle of intersection between two circles formula is defined as the angle between their tangents at either of the intersection points and is represented as ∠A = arccos((((r1)^2)+((r2)^2)-((DBetweenCenters)^2))/(2*r1*r2)) or angle_a = arccos((((Radius 1)^2)+((Radius 2)^2)-((Distance between centers)^2))/(2*Radius 1*Radius 2)). Radius 1 is a radial line from the focus to any point of a curve, Radius 2 is a radial line from the focus to any point of a curve and Distance between centers is the distance between two centers of circle.
How to calculate Angle of intersection between two Circles?
The Angle of intersection between two circles formula is defined as the angle between their tangents at either of the intersection points is calculated using angle_a = arccos((((Radius 1)^2)+((Radius 2)^2)-((Distance between centers)^2))/(2*Radius 1*Radius 2)). To calculate Angle of intersection between two Circles, you need Radius 1 (r1), Radius 2 (r2) and Distance between centers (DBetweenCenters).
