Answer» First the total circle area of RADIUS 49 m is = 22/7 × 49 × 495 = 7546 sq.m Next, the circle without the path with radius 49 - 3.5 = 45.5 = 22/7 × 45.5 × 45.5 = 6506.5 sq.m Area of path = Big circle area - small circle area = 7546 - 6506.5 = 1039.5 sq.m Cost of paving the path = 1039.5 × 30 = RS. 31,185 Therefore, Rs 31185 is needed to pave the path HOPE THIS HELPS YOU........ |
