hiii!!!
here's ur answer...
given the diameter of the circular flower bed = 100cm = 1m
therefore radius of the flower bed = 1/2 = 0.5m
circumference of the circular flower bed = 2πr
= 2 × 22/7 × 0.5
= 22/7m
ATQ, the cost of fencing is rs w at the rate per m.
hence, total cost of fencing = 22/7 × 2
= 44/7
= rs 6.28 (approx.)
hope this helps..!!
