Question
Find the center-radius form of the circle with the given equation. Determine the coordinates of the center, find the radius, and graph the circle.$$x^{2}+y^{2}-2 y-3=0$$
Step 1
The standard form of a circle is given by $(x-h)^{2}+(y-k)^{2}=r^{2}$, where $(h,k)$ is the center of the circle and $r$ is the radius. The given equation is $x^{2}+y^{2}-2y-3=0$. Show more…
