If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3. The correct option is D.

<h3>What is the equation of the circle with radius r units, centered at (x,y)?</h3>

If a circle O has a radius of r units length and it has got its center positioned at (h, k) point of the coordinate plane,

then, its equation is given as:

$(x-h)^2 + (y-k)^2 = r^2$

The equation of unit circle is

$(x-h)^2 + (y-k)^2 = 1\\\\x^2 + \dfrac{\sqrt{3} }{3}^2 = 1\\\\x^2 + \dfrac{1 }{3} = 1\\\\\\x^2 = 1 - \dfrac{1 }{3} \\\\x^2 = 2/3\\$

Thus, x = √2/ 3

If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3.

The correct option is D.
