. As shown in the diagram above, a sphere is placed on the top of an incline. It rolls down the incline without slipping in exactly 50 turns. The radius of the sphere is  4. A set of concentric circles of integer radii 1, 2, …… N is shown in the figure above. An ant starts at point A¬1, goes round the first circle, returns to A1, moves to A2, goes round the second circle, returns to A2, moves to A3 and repeats this until it reaches AN. The distance covered by the ant is

(1) N (N + 1)Π           (2)2N Π + N          (3) Π (N+1) N + N – 1        (4) Π (N-1) N + N – 1 5. The figure above shows an infinite series of triangles, in which r1> r2> r3 …. What is the total length of the solid line segments in the figure ? Ans:- 2
