Question 874869
Imagine the circle centered at the origin on a cartesian coordinate system, and the chord in the circle is parallel to the x-axis, and the center of the chord intersects the y-axis, cutting the chord into two pieces of length 8 cm.


The circle is {{{x^2+y^2=100}}}.  Notice that the x coordinates for the endpoints of the chord are x=-8 and x=8.  Use either of these to find the y value.  This y value is the distance from the chord to the center of the circle.
