Answer» 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..!! |
