suppose the diameter of a circle is 20in. long and a chord is 16in. long. What is the distance from the center of the circle to the chord

Draw a radius from the center to the end of the chord. THe draw a radius from the center perpendicular to the chord. You have a right triangle, one side is radius (given), one side is 1/2 chord, and your distance. Use the pyth theorm to solve.
