Find the equation of a circle with Centre ( – 3, – 2) and radius 6

Answer:

The general form of the equation of a circle is: (x – h)2 + (y – k)2 = r2

(h, k) is the center of the circle. r is the radius of the circle.

Substituting the center and radius of the circle in he general form,

(x – ( – 3))2 + (y – ( – 2))2 = 62

(x + 3)2 + (y + 2)2 = 36

 

 

 

 

 

 

The equation of a circle with Centre ( – 3, – 2) and radius 6 is,

(x + 3)2 + (y + 2)2 = 36
