A circle has a chord that goes from #( 5 pi)/4 # to #(4 pi) / 3 # radians on the circle. If the area of the circle is #64 pi #, what is the length of the chord?
The length of the chord is
Calculate the radius of the circle from the area of the circle.
area of circle =
Now calculate the coordinates of the endpoints of the chord.
Let's represent the coordinates for the endpoint at
, the coordinates for the endpoint at
