Question

Write the equation of the circle in standard form: Center (7,0) R=1

Answer 1

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

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

1) Plug in the given center (7,0)

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

2) Plug in the radius (1)

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

I hope this helps!
