Mice21 [21]

Answer:

(x-7)^2+y^2=1

Step-by-step explanation:

Hi there!

Equation of a circle: (x-h)^2+(y-k)^2=r^2 where the circle is centered at (h,k) and the radius is r

<u>1) Plug in the given center (7,0)</u>

(x-7)^2+(y-0)^2=r^2\\(x-7)^2+y^2=r^2

<u>2) Plug in the radius (1)</u>

(x-7)^2+y^2=1^2\\(x-7)^2+y^2=1

I hope this helps!
