(x - 5)2 +(y + 2)2 =16

Question

Radius 

Center 

Answer 1

Assuming that those 2's are squares, then you are in the standard circle form. The center can be thought of as having coordinates where the x-5 and the y+2 would be 0. Hence, the center is at (5,-2). The part on the right is the square of the radius. Since 4 squared equals 16, your radius is 4.

 

Center (5,-2)

Radius 4
