Question 193426
<font face="Garamond" size="+2">


The equation of a circle with center at (h,k) and radius r is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (x - h)^2 + (y - k)^2 = r^2]


Since you are centered at the origin, h and k are both zero, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x^2 + y^2 = 100]


Just pick x = 10, x = -10, and x = 0 and substitute these values then solve for y.  That will give you 4 of the 6 points you need.  Then pick another value for x other than zero on the interval -10 < x < 10 to get your last two points.
