Question 140200
if the line is from the center of the circle to the center of the chord...it is a perpendicular bisector


the line, half the chord, and the radius form a right triangle; with the radius as the hypotenuse


so 6^2+(16/2)^2=r^2 __ 36+64=r^2 __ 10=r


if the radius is 10, then the diameter is 20
