Question

PLEASE I NEED HELP!
A circle has its center at (-1, 2) and a radius of 3 units. What is the equation of the circle?

(x - 1)2 + (y + 2)2 = 3
(x + 1)2 + (y - 2)2 = 3
(x + 1)2 + (y + 2)2 = 9
(x + 1)2 + (y - 2)2 = 9

Answer 1

(x + 1)2 + (y - 2)2 = 9


general equation>>
(x -x1)2 + (y - y1)2 = r^2

where (x1,y1) is the center of the circle

Answer 2

sorry for the late reply hope youre still there @princeharryyy
