13. Find the center and radius of the circle with equation (x-5)^2+(y+6)^2=9

Answer 1

a circle with center \((h,k)\) has the equation\[(x-h)^2+(y-k)^2=r^2\]

Answer 2

Where r-->radius of circle

Answer 3

Can you follow the instruction?

Answer 4

as turingtest wrote , match up
\[(x-5)^2+(y+6)^2=9\]
with
\[(x-h)^2+(y-k)^2=r^2\]
identify \(h\) and \(k\) and \(r\)

Answer 5

r = 3 and the center is (5,-6)

Answer 6

yes :)
