The equation of a circle is (x-3)^2+(y+8)^2=36. Relative to the standard equation of a circle (x^2+y^2=r^2), how has this circle been shifted? What is the radius of the circle?

Respuesta :

The circle has been shifted 3 units to the right and 8 units down.
The radius of the circle would be square root of 36,  which is 6

Radius= 6 units
Translation= 3 units horizontally right , 8 units vertically down
the circle shifts to the right 3 units and down 8 units. It's radius is 6
