2 square root 5
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The equation of the circle is equal to
where
(h,k) is the center and r is the radius of the circle
In this problem we have
center at (0,0) and radius equal 6 units
so
Remember that
If a point lie on the circle, then the point must satisfy the equation of the circle
Substitute the x-coordinate of point Q in the equation of the circle and solve for the y-coordinate of point Q
For x=4
simplify
The point Q lie on the first Quadrant (see the picture)
The y-coordinate is positive
therefore
The y-coordinate of point Q is![2\sqrt{5}](/tpl/images/0464/9897/0bea1.png)
