there is a `standard form` for circle too

ganeshie8 · Answer

do you have notes handy ? 
can u look up quick and see if u can find the `standard form of circle` ? :)

anonymous · Answer

(x−h)2+(y−k)2=r2

ganeshie8 · Answer

yes ! thats the equation :

center = (h, k)
radius = r

ganeshie8 · Answer

compare the options with this standard form, and see if u can figure it out

i knew that lol
