Answer 2

Step-by-step explanation:Radius of the circular garden (r) = 56 m ∴ Circumference of the circular garden (c) = 2πr = 2 x 22/7 x 56 = 352 m

∴ Length of the wire required to put 1- round fence = Circumference

∴ Length of wire required to put a 4- round fence = 4 x Circumference = 4 x 352 = 1408 m

fence around garden = rs 60 per meter

∴ Total cost = length of wire required x cost of the wire

1408*60
