Question

Find the equation of the circle with the given characteristics.
Center: (-2, -1) Radius: 1
The solution is

Answer 1

Answer:

$(x+2)^2+(y+1)^2=1$

Step-by-step explanation:

Equation of a circle:

• $(x-h)^2+(y-k)^2=r^2$
• Center ==> $(h,k)$
• Radius ==> $r$

Plug in known information:

$(x-h)^2+(y-k)^2=r^2$

$(x-(-2))^2+(y-(-1))^2=(1)^2$

$(x+2)^2+(y+1)^2=1$
