Question

general form of the equation of Center (0,0) radius 3

Answer 1

x^2 +y^2 = 9

Answer 2

\[x^2 + y^2 = r^2 \]\[x^2 + y^2 = 9\]

Answer 3

what if the center is changed?

Answer 4

\[(x -h)^2 +(y-k)^2 = r^2\]
\[(h,k) \text{ is the center}\]

Answer 5

but thats standard form

Answer 6

oh I see

Answer 7

lol

Answer 8

do i have to put it in standard form then change it? or is there another way

Answer 9

\[x^2 + y^2 +2gy +2hx +c=0\]
\[(-h,-g)\text{ is the center }\]
