The circle is centered at (5, βˆ’7) and has a radius of 7.

Step-by-step explanation:

The standard form of the equation of a circle with center (a,b) and radius r is given as:

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

The given equation is

( {x - 5)}^{2} + {(y + 7)}^{2} = 49

We rewrite to look like the stay form:

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

We now compare the two equations to get:

a=5, b=-7 and r=7.

Therefore the circle is centered at (5,-7) and has a radius of 7
