How many units in a unit circle?
A unit circle is a circle with radius equal to one.
What is the equation of the unit circle?
For a circle with center at (a,b), and radius r: (x-a)2 + (y-b)2 = r2
What kind of unit does a circle have?
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.
What is the radius of a circle whose circumference is 6.28?
The radius is 1 (0.999) unit.
What is the radius of a circle with a diameter of 2?
radius = diameter / 2 = 2/2 = 1 unit
What is the circumference of a unit circle?
Since the radius of the unit circle is 1, the circumference is 2 x pi.
What is the unit circle?
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.
Why is the unit circle called two pi?
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.

How is pi in relation to a circle?
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).
What is the area of a circle which has a radius that is equal to1?
A circle with a radius of 1 unit has an area of 3.14 square units.
