# Find the center and radius of the circle with equation x2 + y2 – 6x + 10y + 9 = 0.

To determine

To find: The center and radius of the circle with equation x2+y26x+10y+9=0.

Explanation

Formula used:

The equation of the circle is (xh)2+(yk)2=r2, where the center of the circle is at the point (h,k), r is the radius of the circle.

Calculation:

It is given that the equation of the circle is x2+y26x+10y+9=0.

Simplify the above equation as follows,

x2+y26x+10y+9=0x26x+9+y2+10y+2525=0(x3)2+(y+5)2=25(x
