Question

Center (13,-13) radius 4 write the equation

Answer 1

`(x-13)^2+(y+13)^2=16`

Explanation:

The equation of a circle is
`(x-h)^2+(y-k)^2=r^2`.

The center of a circle is written in the format (h, k).

So, it is given that h = 13, k = -13, and r = 4.

Substituting the values into the formula above gets us the following,

`(x-13)^2+(y+13)^2=16`
