Intersecting chords theorem outside circle
WebL is 1/2 the chord length. r is the same radius you already found. So we already know 2 sides for this triangle and just need to solve for L and double it to get the second chord length. r^2=a^2+L^2. L^2=r^2-a^2 = 35.23^2-17^2. L= sqrt (35.23^2-17^2) L=30.85. Just double that to get the length of the second cord. WebFeb 7, 2024 · Write down the chord length formula: c = 2 · √ (r² - d²). Here: r is the radius; c is the chord's length; and. d is the chord's distance to the circle's center. Replace r and d with their respective values. The result …
