Question

2. Find the center and radius of the circle with equation (x-6)2+ (y + 5)2 = 9.
C center (6,-5); radius 9
center (-6, 5); radius 3
C center (6, -5); radius 3
C center (-6, 5); radius 9

Answer 1

Answer:

Center (6 , -5)   and radius = 3

Step-by-step explanation:

The Standard equation of circle can  be written as

(x - a)² + (y - b)² = r²

with center (a , b)   and radius  = r

Now from given circle equation

(x - 6)² + (y +5)² = 9

so, from here center of circle (6 , -5) and radius = 3
