Diameter of the field = 56m.
Radius = d/2 = 56/2m = 28m.
Therefore circumference =2πr = 2 ×22/7 ×28m = 176m.
Rate of fencing =$80/m
Therefore cost of fencing = $80 × 176m = $14080
Radius = d/2 = 56/2m = 28m.
Therefore circumference =2πr = 2 ×22/7 ×28m = 176m.
Rate of fencing =$80/m
Therefore cost of fencing = $80 × 176m = $14080
Diameter = 56m
Radius = 56/2 = 28m
Circumference = 2*22/7*28
= 176m
Cost of fencing = 176*80
= Rs 14,080
Radius = 56/2 = 28m
Circumference = 2*22/7*28
= 176m
Cost of fencing = 176*80
= Rs 14,080
