Find the equation of a circle with center at $(h, k)$ and radius $1$
Answer 1
Amelia Mitchell
The general equation of a circle with center $(h, k)$ and radius $r$ is given by:
$ (x – h)^2 + (y – k)^2 = r^2 $
For a unit circle, the radius $r = 1$. Therefore, the equation becomes:
$ (x – h)^2 + (y – k)^2 = 1 $
Answer 2
Lucas Brown
The equation of a circle is given by:
$ (x – h)^2 + (y – k)^2 = r^2 $
For a unit circle, $r = 1$. Substituting $r = 1$ into the equation, we get:
$ (x – h)^2 + (y – k)^2 = 1 $
