Find the cost of fencing a field which is in the shape of sector with angle `90^(@)` and radius 56 m at the rate of Rs.5 per metre. The following steps are involved in solving the above problem. Arrange them in sequential order. (A) `therefore` The cost fencing = Perimeter`xx` Rate per metre`=200xxRs.5` (B) The perimeter of the sector `=(theta^(@))/(360^(@))xx2pir+2r=(90^(@))/(360^(@))xx2xx(22)/(7)xx56+2xx56`. (C) The perimeter of the sector = 200 m (D) The cost of fencing = Rs. 1000A. CDABB. ABCDC. BCADD. CBAD
