Solution
For this case we have the following equation given by:
[tex](x-2)^2+(y-5)^2=49[/tex]The general equation of a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]And for this case by direct comparison we have:
[tex]r^2=49[/tex]Then we have:
[tex]r=\sqrt[]{49}=7[/tex]And the center si given by C=(h,k)
From the equation given we have:
[tex]C=(2,5)[/tex]
