Region between Two Concentric Circles
Think about two circles. They’re like round shapes, one inside the other sharing the same center but with different sizes. Now, the space between the edges of these circles kind of like the space between two hula hoops is what we call the “region between two concentric circles”.
Imagine these circles like a target—a smaller bullseye inside a larger circle. The space between these circles is like the area on the target board between the center and the outer ring. It’s this space that’s interesting to explore when we’re working with shapes and measurements related to circles.
The area between two concentric circles is the region lying between their circumferences. It’s akin to a circular belt around the smaller circle extending up to the larger circle’s circumference.
An Annulus is the region between two concentric circles. To find the area A annulus of this region, subtract the area of the smaller circle from the area of the larger circle and the formula for the same is,
Area of Annulus = π(r22 − r12)
Concentric Circles
Concentric circles are defined as two or more circles that share the same center point, known as the midpoint, but each has a different radius. If circles overlap yet have different centers, they do not qualify as concentric circles. According to Euclidean Geometry, two concentric circles must have two different radii. The space between the circumference of these two circles is called the annulus of a circle.
In this article, we will learn about concentric circles, the theorem on concentric circles, the region between the concentric circles, Concentric Circle Equations, and Concentric Circles examples in detail.
