diameter of circular garden=21m
radius of circular garden= 21/2 m
rope needed for fencing= 2πr =2*22/7*21/2=66m
cost of fencing 1m=22/7
cost of fencing 66 m = 66*22/7= rs 207.428571
radius of circular garden= 21/2 m
rope needed for fencing= 2πr =2*22/7*21/2=66m

D 21m
r 10.5
need of wire = circumference of circle
formula 2×22/7×r
2×22/7×10.5
44×10.5÷7
462÷7
66 m
cost of wire 1m =22/7
then 66 m =66×22/7
207.4 rupees.
