document.write( "Question 393287: If a circle has a diameter of nine inches and a chord that is five inches long, what is the distance from the chord to the center of the circle, to the nearest hundreth of an inch. There was not a picture in the textbook that went along with this problem. Is there a formula to solve this? If so, what is it? Thank you! \n" ); document.write( "

picture two radii of the circle
\n" ); document.write( "one drawn through the center of the chord
\n" ); document.write( "and the other, drawn to the end of the chord\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the one through the center of the chord is a perpendicular bisector of the chord\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a right triangle is formed by half the chord,
\n" ); document.write( "the portion of the radius to the center of the chord (this is the distance from chord to center),
\n" ); document.write( "and the radius to the end of the chord (this is the hypotenuse)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "by Pythagoras ___ (5/2)^2 + x^2 = (9/2)^2
\n" ); document.write( "
\n" );
