Which equation represents a circle with a center at (–3, –5) and a radius of 6 units? (x – 3)2 + (y – 5)2 = 6 (x – 3)2 + (y – 5)2 = 36 (x + 3)2 + (y + 5)2 = 6 (x + 3)2 + (y + 5)2 = 36

Option D. (x + 3)² + (y + 5)² = 36

Step-by-step explanation:

We have to find the equation of a circle given with a center at (-3, -5) and radius of 6.

Since the standard equation of a circle is

where (h, k) is the center and r is the radius.

Now we form an equation of a circle given with center (-3, -5) and radius = 6 units.

(x + 3)² + (y + 5)² = 6²

(x + 3)² + (y + 5)² = 36

Therefore Option D is the answer.
