    Question

    The radius of a circle is 13 cm, and the length of the

    chord is 10 cm. Find the distance between the chord and the centre of the circle.  
    A 5 cm Correct Answer Incorrect Answer
    B 12 cm Correct Answer Incorrect Answer
    C 10 cm Correct Answer Incorrect Answer
    D 13 cm Correct Answer Incorrect Answer

    Solution

    Length of the chord = 10 cm  So, half of the length of the chord = 5 cm  So, distance between the chord and centre = √ {13² - 5² } = √ {169 - 25} = √ {144} = 12 cm
