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

Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..

Radius = 1111

If you mean: x^2 + y^2 = 121 then the radius is the square root of 121 which is 11
That's the equation of a circle with its center at the origin and a radius of 8.
The radius is sqrt(12) = 3.464 (rounded)
Centre = (0,0), radius = sqrt(5)
