A standard dartboard features a total of 20 concentric rings. These rings are divided into scoring sections for points, with the outermost ring representing the lowest score and the innermost bullseye circle representing the highest. Additionally, there are two smaller circles for the bullseye, which are typically divided into an inner and outer bullseye.

Concentric rings in water are called ripples. Ripples are small waves that form on the surface of the water when it is disturbed.

Ice forms by depositing concentric rings through a process called ice accretion, where supercooled water droplets freeze upon contact with a surface. This can happen on objects like tree branches, power lines, or even airplane wings. The concentric rings are created as multiple layers of ice build up over time, forming a ring-like structure.
