To solve this question, we need to interpret the equation of a circle, to find that:
The circle is centered at (5, −7) and has a radius of 7.
-------------------
Equation of a circle:
The equation of a circle, with center and radius r, is given by:
In this question:
The following equation of a circle is given:
-------------------
Center:
We have to compare the two equations, to find and . So
As for y:
Thus, the circle is centered at (5,-7).
-------------------
Radius:
Again, comparing both equations:
So the radius is 7(diameter 2*7 = 14).
-------------------
With the center and radius found, the correct option is:
The circle is centered at (5, −7) and has a radius of 7.
