A unit circle is a circle with radius equal to one.

It is unknown who created the unit circle. Pythagoras did a lot of work related to the unit circle. In ancient times, Greek, Indian, and Arabian mathematicians used the unit circle.

A unit circle is not normally called 2 pi. Because the radius length measure of the unit circle is 1 unit, then the circumference of a unit circle is 2*pi, and its area is pi.

The unit circle is a circle that can be used to find trigonometric functions. The equation of the unit circle is x^2 + y^2 = 1. So it is any circle with radius 1.

There really isn't much to memorize. The unit circle is a circle with a radius of 1.

A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.

A unit circle is one that has a radius of one. One = Unit, and hence the name.

Pi over 12 on a radian unit circle is a little more than a quarter of the circle. Radian units are an alternative to degrees.

To calculate the area of a unit circle you should use the equation x2+y2=1. The unit circle equal area of 1. You can find out more information on the mathisfun website for deeper explanation.

The area of a 6 unit circle is: 28.27 square units.

Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).

A unit circle is in the coordinate plane where both axes are measured in real numbers. The imaginary circle is in the complex plane in which one axis (horizontal) measures the real component of a complex number and the other axis measures the imaginary component.
