Unit Circle - Math is Fun
The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here.

In trigonometry, the unit circle is a circle with of radius 1 that is centered at the origin of the Cartesian coordinate plane. The unit circle helps us generalize trigonometric functions, making it easier for us to work with them since it lets us find sine and …
Unit circle - Wikipedia
In mathematics, a unit circle is a circle of unit radius —that is, a radius of 1. [1] Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.

1.1: The Unit Circle - Mathematics LibreTexts
The unit circle is the circle of radius 1 that is centered at the origin. The equation of the unit circle is \(x^2+y^2 = 1\). It is important because we will use this as a tool to model periodic phenomena.
Radius of a Circle - Formula | What is Radius? | Radius Formula
The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The distance from the center point to any endpoint on the circle is called the radius of a circle. Learn about the radius formulas with solved examples with Cuemath.
