Write the equation of a circle givin by (x-3)^2+(y+7)^2=4

Answer:8Step-by-step explanation:(x+4)2+(y−7)2=64This is the form of a circle. Use this form to determine the center and radius of the circle.(x−h)2+(y−k)2=r2Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin.r=8h=−4k=7The center of the circle is found at (h,k).Center: (−4,7)These values represent the important values for graphing and analyzing a circle.Center:  (−4,7) Radius: 8
