What is the equation of the circle shown below?
1 answer:
Answer:
( x+2)^2 + ( y+2) ^2 = 9
Step-by-step explanation:
The center is at (-2,-2)
The radius is 3 which is the number of units from the center to the circles edge
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--2) ^2 + (y--2) ^2 = 3^2
( x+2)^2 + ( y+2) ^2 = 9
