## anonymous one year ago The equation of a circle whose center is at ( 4,0 ) and radius is length 2 ( square root ) 3

$(x-h)^2+(y-k)^2=r^2 \\ \text{ has center } (h,k) \\ \text{ and radius } r$

your center is given has (4,0)=(h,k) this tells you to replace h with 4 and k with 0 you are also given radius which is called r above so replace r with whatever number it is you have there 2sqrt(3)?
