AC is the diameter of the circle and it must be 6.
Triangle ABC is 30-60-90 and thus, BC = 6 / √3.
Area of triangle = 1/2 * 6 * 6 / √3.
we get 18 / √3
6 * √3 * √3 / √3
Thus, 6*√3
Triangle ABC is 30-60-90 and thus, BC = 6 / √3.
Area of triangle = 1/2 * 6 * 6 / √3.
we get 18 / √3
6 * √3 * √3 / √3
Thus, 6*√3
