Center:(4,7)Radius:10X-intercepts:NoneY-intercepts:None

Steps

Step 1 :The equation of a circle is given by (xh)2+(yk)2=r2 where (h,k) is the center of the circle and r is the radius. Comparing this with the given equation, we can see that the center of the circle is (4,7) and the radius is 10.

Step 2 :To find the x-intercepts, we set y=0 in the equation and solve for x. Similarly, to find the y-intercepts, we set x=0 in the equation and solve for y.

Step 3 :The x-intercepts and y-intercepts are complex numbers, which means the circle does not intersect the x-axis or y-axis.

Step 4 :Final Answer: The center of the circle is at point (4,7), the radius is 10, and there are no real x-intercepts or y-intercepts. The circle does not intersect the x-axis or y-axis. The graph of the circle would be a circle centered at point (4,7) with a radius of 10, and it would not intersect the x-axis or y-axis.

Step 5 :Center:(4,7)Radius:10X-intercepts:NoneY-intercepts:None
