Question

For the equation of a circle `(x - 4)^2 + (y - 2)^2 = 9`, how do you determine the coordinates of the center of the circle?

Answer 1

The general equation of the circle is:
`(x-h)^2+(y-k)^2=r^2`
Where r is the radius and (h,k) is the center of the circle.
From here you should be able to identifying
`r=sqrt(9)` and the center well I will let you figure it out...

Good luck,
