Question

1 Point The circle below is centered at (-3, 2) and has a radius of 3. What is its equation?

Answer 1

Answer:

(x + 3)^2 + (y - 2)^2 = 9

Step-by-step explanation:

Equation for a circle:  (x – h)^2 + (y – k)^2 = r^2

Step 1:  Determine what h, k, and r are

h is the x value of the point:  -3

k is the y value of the point:  2

r is the radius of the circle:  3

Step 2:  Plug in and solve

(x – h)^2 + (y – k)^2 = r^2

(x – (-3))^2 + (y – (2))^2 = (3)^2

(x + 3)^2 + (y - 2)^2 = 9

Answer:  (x + 3)^2 + (y - 2)^2 = 9
