Question

What is the equation of a circle with center (-3,-5) and radius 4?

Answer 1

Answer:   D) (x + 3)² + (y + 5)²  = 16

Step-by-step explanation:

The equation of a circle is: (x - h)² + (y - k)² = r²    

where (h, k) = center   and    r = radius

Given: (h, k) = (-3, -5)  r = 4

Equation: (x - (-3))² + (y - (-5))² = 4²

                 (x + 3)²  +  (y + 5)²  = 16
