Question

Need help with a Conic Sections equation?
Identify the Center and Radius for the following equation:

maddy1251 · Answer

$$x^{2}+y^{2}=7$$

maddy1251 · Answer

I believe the radius to be about 2.6.

imqwerty · Answer

center =(0,0)
radius =sqrt{7}

imqwerty · Answer

yes sqrt{7}=2.6

Thank you @imqwerty ! I didn't know what to do with the (x,y) values. Much thanks :-)

imqwerty · Answer

(: 
np 
did u get the center?

maddy1251 · Answer

@imqwerty yeah :) I did! I kinda thought it would be either (1,1) or (0,0), just wasn't 100% which it would be

imqwerty · Answer

ok when ever u have this kinda thing compare it with equation of circle

equation of circle-$$(x-h)^2 +(y-k)^2=r^2$$
where (h.k)=center coordinates
r=radius of cricle

johnweldon1993 · Answer

Just remember the equation of a circle

$$\large (x - h)^2 + (y - k)^2 = r^2$$

(h,k) is your center
