      Question

      The radius of a circle is 17 cm, and the length of the

      chord is 30 cm. Find the distance between the chord and the centre of the circle.  
      A 15 cm Correct Answer Incorrect Answer
      B 8 cm Correct Answer Incorrect Answer
      C 9 cm Correct Answer Incorrect Answer
      D 10 cm Correct Answer Incorrect Answer

      Solution

      Length of the chord = 30 cm  So, half of the length of the chord = 15 cm So, distance between the chord and centre = √ {17² - 15² } = √ {289 - 225} = √ {64} = 8 cm
