## anonymous 4 years ago Find the coordinates for the center and length of radius for this circle. (x - 4)2 + y2 = 12

1. anonymous

center at (4,0) radius is $2\sqrt3$

2. campbell_st

you need to learn the general equation for a circle is $(x - h)^2 + (y - k)^2 = r^2$ The centre is always (h,k) and radius is always r
