The diameter \( AB \) of a circle of radius \( 4 \) is extended to a point \( D \) outside the circle so that \( BD = 5 \). Point \( E \) is chosen so that \( ED = 6 \) and line \( ED \) is perpendicular to line \( AD \). Segment \( AE \) intersects the circle at a point \( C \) between \( A \) and \( E \). Calculate the area of triangle \( ABC \).
