Question 773270: Given a circle with radius "r", express the length of chord "c" in terms of "r and d" when the perpendicular distance from the chord is "d" Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! radius = r
d= distance of chord from center
length of chord = c
half the length of chord ,the radius and the distance from center form a right triangle
(c/2)^2= r^2-d^2
c^2/4 = (r^2-d^2)
c^2=4(r^2-d^2)
