Step 1

state the equation of a circle


(x-h)^2+(y-k)^2=r^2

where;


(h,k)\text{ is the center of the circle and r is the radius of the circle}

The center of the circle is(10,-11). The radius of the circle is 20. We are only concerned with points on the circle that has a y-coordinate of 5.

Step 2

The equation now becomes;


undefined
