    Answer:

    The equation is:

    (x+2)^2+(y-5)^2=49 (simplified if needed)

    or

    (x+2)^2+(y-5)^2=7^2

    Step-by-step explanation:

    The equation of a circle is :

    (x-h)^2+(y-k)^2=r^2 where the center is (h,k) and radius r.

    -So, putting the radius 7 and the center (-2,5) on the equation, would be:

    (x+2)^2+(y-5)^2=7^2

    -when you put them onto that equation, the radius needs to be simplified by the exponent if needed:

    (x+2)^2+(y-5)^2=49
