Proper form first. X2 + Y2 = 1 Y2 = 1 - X2 Y = (+/-) sqrt(1 - X2) -------------------------- zero out the X Y = (+/-) sqrt(1 - 02) Y = 1 ----------------the radius of this circle
That's the equation of a circle with its center at the origin and a radius of 8.
If that equals 16 then the radius is 4
x2 +y2 = R2 =16 = radius 2 R = 4
