Question

Given the equation of the circle below, find the center coordinate of the circle,

and the radius of the circle.
x² + y2 + 4y = 32
Center : (0, 2)
Center : (0, 2)
Center : (0, -2)
Center : (0, -2)
R = 26
R = 6
R = 36
R = 6

Answer 1

Center : (0,-2), R=6

Explanation:

x² + y² + 4 y = 32

x² + y² +4 y+4=36

x² + (y+2)²=36

Center : (0,-2), R=6
