Question

. Find the coordinates of the center and the measure of the radius for a circle whose equation is

(x-8)2 + (y+4)² =12 (3 points)

Answer 1

Radius is 2√3 units

Center is (8,-4)

Explanation:

Compared to the standard form equation of a circle,
`(x-h)^2+(y-k)^2=r^2`, then the radius would be
`r=√(12)=2√(3)` and the center would be
`(h,k)\rightarrow(8,-4)`.
