Best ResponseYou've already chosen the best response.1The equation of a circle with center at (h, k) nad radius r is \(\large (x  h)^2 + (y  k)^2 = r^2\) Compare the equation you were given with the form above. What are your values of h, k, and r?

Best ResponseYou've already chosen the best response.112 and 32 are correct for h and k, respectively, so the center is (12, 32). Be careful with the radius. The right side has to be written as r^2. Then r is the radius. Your right side is 49. How do you write 49 as the square of something?

Best ResponseYou've already chosen the best response.1Correct. \((x−12)^2+(y−32)^2=7^2\) Center: (12, 32) Radius: 7

Best ResponseYou've already chosen the best response.1I have a question for you. In your choices, you have radius only of 49 and 23. Did your equation have 49 or 49^2 on the right side?
