Answer:

A

Step-by-step explanation:

Equation of a circle: (x - h)² + (y - k)² = r², (h, k) is the coordinate of the center and r is the radius of the circle.

h is -3 and k is -3.

Plug in: (x + 3)² + (y + 3)² = r², so c and d are not right.

Radius: A says that the radius of the circle is √37, which is about 6.1, and B says √6.1, which is about 2.5.

The distance of -3 to 3 is 6 units, which means that it is longer than √6.1, which means A is the answer.
