Write an equation of the circle with center (-7, -4) and radius 6 .
siniylev [52]

Answer:

(x+7)^2 + (y+4)^2 = 6^2

or

(x+7)^2 + (y+4)^2 = 36

Step-by-step explanation:

We can write the equation of a circle in the form

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

(x--7)^2 + (y--4)^2 = 6^2

(x+7)^2 + (y+4)^2 = 6^2

or

(x+7)^2 + (y+4)^2 = 36
