Question

write the general form of the equation of the circle.
center: (0,0)
radius: 3
I got: sqrt(x^2 + y^2) = 3

Answer 1

x^2 + y^2 = 9

Answer 2

Nomss, you are correct, as long as you append:
\[\pm \sqrt{x^2+ y^2} = 3\]

Answer 3

\[\sqrt{x^2+y^2}=3\] is only the upper half of the circle

Answer 4

the standard form is what i wrote

Answer 5

him1618 is exactly right.

Answer 6

their answers are correct :)

good luck

Answer 7

actually this is what i had too: x^2 + y^2 = 9
thanks guys :)

Answer 8

um no no. i need general form...

Answer 9

generel form ? can u explain more ?

Answer 10

Ax^2 + Ay^2 + Dx + Ey + F = 0 A != 0

Answer 11

so you got it by yourself !

Answer 12

Yeah, \[x^2 + y^2 = 9\] is the general form

Answer 13

Good job bro =D !
