Question

Write the equation of the circle with center (5,-5) and radius 6.

Answer 1

Answer:

(x-5)^2 + (y-(-5)^2 = 36

Step-by-step explanation:

Use the formula:

(x-a)^2 + (y-b)^2 = r^2

where (a,b) are coordinates of the center (r), the radius.

So...

a = 5, b = -5, and r = 6

Now...

(x-5)^2 + (y-(-5)^2 = 6^2
