A circle in the xy-plane with center (4,0) passes through point (7,4). Which of the following is the equation of the circle? () A. (x-4)^2+y^2=9 B. (x-4)^2+y^2=25 C. (x-4)^2+ y^2 =5 D. (x+4)^2+y^2=5...
Remember that using the equation: (x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius, we can use the fact that the center is located at (-5,-5) to get: (x+5)^2+(y+5)^2=r^2. Now substitute in the values x=0 and y=-17 to solve for r o...
