Question 876552
Put the center of this circle on the origin of a cartesian coordinate system.  Show this chord of 10 cm horizontally above the x-axis with the chord's endpoints on the circle.  The x-coordinates are -5 and 5.  Use the equation of the circle to determine the y value, which is the distance from the chord to the center of the circle.
