Center:
Radius:
Explanation:
We need to know the center and radius of the circle before we can write the equation. We only need to focus on
First, notice how we have the same x-value and two y-values in our equation. That means we have a diameter! As you know, a diameter is two times the radius:
Next, let's find the center. The center is the midpoint between our two coordinates, so let's just subtract our radius from
All we have to do next is plug our values into the standard formula for a circle:
