The diameter of the circular flower garden = d = 70 m = 2r Circumference of circular flower garden = 2πr = πd
227×70 = 220 m
The unit cost of fencing the circular garden per metre = ₹15 per meter
The cost of fencing = circumference × unit cost = 220 × 20 = ₹4400
Hence,The cost of fencing the circular flower garden = ₹4400
