A circle with center (-3,0) is between two x values (-5,-1). How can I find Radius?

Answer 1

Since the circle is between, x = -1 and x = -5, you know that the diameter of the circle is -1 - (-5) = 4 units

So the radius is 2. That fits because the center of the circle would be x = two units either way

Or, center = -5 +2 = -3, or, center = -1 -2 = -3
