Answer:

The center is (7,-2)

The radius is [tex]r=\sqrt{37}\ units[/tex]

Step-by-step explanation:

we know that

The equation of the circle in standard form is equal to

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

where

(h,k) is the center and r is the radius

in this problem we have

[tex](x-7)^{2}+(y+2)^{2}=37[/tex]

therefore

The center is (7,-2)

The radius is

[tex]r^{2}=37\\ r=\sqrt{37}\ units[/tex]
