So our equation currently is ⇒
<u>Let's first move all the constant to one side and group 'like variables' together</u>:
<u>Now lets complete the square of both equations</u>
<u><em>Now we know the circle's general equation format is</em></u>:
⇒
- (h, k) ⇒ coordinate of the center of the circle
- r ⇒ length of radius of circle
<u>Thus the radius of the circle is 7</u>
<u></u>
Hope that helps!
