of the circle, its radius as well as the width of the rectangle are both 2cm, and the areas of the circle and the rectangle are the same. So the length of the rectangle is cm, and the simplest integer ratio between the shaded part and the circle area is .相关...
D OS and OT are equal since they are radii of the circle. Hence, △ SOT is isosceles. Therefore, S=T=51°. Recalling that the angle sum of a triangle is 180°, we get S+T+y=51°+51°+y=180°. Solving for y gives y=78°. The answer is (D).反馈...
