ThankssssAnswer by RAY100(1637)   (Show Source): You can put this solution on YOUR website!Lets use a rough sketch to define this situation. . draw a circle. Then draw a radius in the horizontal to right position. If we then draw a chord, perpendicular to the radius, about 2/3 way out on radius. Now finally draw a line from the center of the circle, to where the chord intercects the circle. This last line is a radius, pls label "r". It is also the hypotenuse to a right triangle, formed by the initial horizontal radius, and the perpendicular chord. This right triangle can be understood using the pythagorean theorem, c^2 = a^2 +b^2. Generally, this is all that is required. Please remember also that the total chord is bisected into two equal lengths by the perpendicular radius. Hopefully this helps your ubderstanding.
