Answer 1

9514 1404 393

Answer:

  (x +5)² +(y -2)² = 36

Step-by-step explanation:

The radius is half the diameter, so is 12/2 = 6.

The standard form equation for a circle is ...

  (x -h)² +(y -k)² = r² . . . . . . circle centered at (h, k) with radius r

For the given parameters, the equation is ...

  (x +5)² +(y -2)² = 36
