Answer:
A
Step-by-step explanation:
Equation of a circle: <em>(x - h)² + (y - k)² = r²</em>, <em>(h, k) is the coordinate of the center and r is the radius</em> of the circle.
<em>h is -3 and k is -3</em>.
Plug in: <em>(x + 3)² + (y + 3)² = r²</em>, so <em>c and d are not right</em>.
Radius: <em>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</em>.
The distance of <em>-3 to 3 is 6 units</em>, which means that it is longer than √6.1, which means A is the answer.
