Question

Write the equation for a circle that satisfies the given conditions.

Answer 1

The standard form of a circle is:

`(x-a)^2+(y-b)^2=r^2`

Your center is
`(-10, -6)` and your radius is
`9`

Plug them into the equation and you get

`(x-(-10))+(y-(-6)) = 9^2`

`(x+10)^2 + (y+6)^2=81`

The correct answer is D.
