WebQuestion: Find the length of the chord of a circle where the radius is 7 cm and perpendicular distance from the chord to the center is 4 cm. Solution: Given radius, r = 7 … WebMay 6, 2016 · 2 Answers. Sorted by: 2. Try this: h = r − w ⋅ sin ( 90 − a) Notice h is the difference between the radius and the height of the 79 - 79 - r triangle. That height will be w sin θ, where θ is the central angle of that triangle. However, the angle listed as a is complementary to θ, hence w sin ( 90 − a). Share.
