THE RADIUS OF CIRCULAR GARDEN=56M. WE WANT 4 CIRCULAR FENCE=56×4=224M. THE COST PER METER=₹40

Answer 2

Answer:

56268.8 rupees

Step-by-step explanation:

given radius(r) of circular garden is 56m

we need to the find the fence of the circle that means perimeter of the circle

so, perimeter of the circle(p) is 2πr

p=2πr

p=2(3.14)(56m)

p=351.68m

for one meter(per meter) the cost of fence is cost*perimeter

cost/meter=40*351.68

=14067.2

the cost of fence of one round is

cost/meter i.e. 14067.2

r the cost of fence of 4 rounds is 4(cost/meter)

4(14067.2)

56268.8 rupees
