Question

A circle is centered at (5, −9) and has a radius of 12. Which of the following is the equation for this circle? (x − 5)2 + (y + 9)2 = 12 (x − 5)2 + (y + 9)2 = 144 (x + 5)2 + (y − 9)2 = 144 (x + 5)2 + (y − 9)2 = 12

Answer 1

Answer:

(x-5)^2 + (y+9)^2 = 144

Step-by-step explanation:

The equation of a circle can be written as

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

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

(x-5)^2 + (y- -9)^2 = 12^2

(x-5)^2 + (y+9)^2 = 12^2

(x-5)^2 + (y+9)^2 = 144
