Finding the Length of a Segment in a Circle

In a circle, the radius measures 8 cm. A diameter line is drawn, and a line segment is drawn from one end of the diameter to a point on the circumference of the circle that is perpendicular to the diameter. What is the length of this line segment?

Use the Pythagorean theorem to assist you in finding the answer, where the circle is centered at the origin (0, 0) on the coordinate plane.
