Question 1123260: There is a square with side length k. Inside the square is a single circle tangent to all four sides. Inside the image, as a whole, is an equilateral triangle, with base at the bottom of the square and top of the triangle ABOUT 3/4 of k (no height was actually given). If the picture in your mind is right (draw it out), what is the area of the shaded region in the bottom right corner where the circle, square, and triangle all meet? (this does not include the entire right side, which would lose the point of the equilateral triangle) (in simple words, it�s the region below the circle to the right, but stopped where the equilateral triangle intersects the square) This is a very hard problem, and doubt anybody can solve it.
