An isosceles triangle is inscribed in a circle of fixed radius R and centre O. What is the minimum area of the region outside the triangle and inside the circle?

The minimum would correspond to an equilateral triangle inside the circle.
The area outside the triangle is in that case (pi - 1.5sqrt3)R^2 = 0.5435 R^2
