Best answer

Radius of the circular garden (r) = 56 m 

∴ Circumference of the circular garden (c) = 2πr

∴ 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

∴ Cost of wire per meter = Rs 40 

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

= 1408 x 40 

= Rs 56320

∴ The cost to put a 4-round fence around the garden is Rs 56320.
