Answer has to be in exact form.Find the area of a segment formed by a chord 8" long in a circle with radius of 8".

  • geometry -

    look at the triangle formed by the chord and the radii.
    Don't you have an equilateral triangle ?
    That would make the central angle = 60°
    So the area of the SECTOR is 1/6 of the area of the circle.
    If you subtract the area of the equilateral triangle you would be left with the area of the segment

    In your previous post, I showed you how to find the height of such a triangle.
    So the problem should be easy for you now.
