A circular flower bed has a diameter of 100 cm .a metal boundary costing rs 2per meter placed around it. findlength of metal boundary that will be required to fence the flower bed twice.

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..!!
