Question

14. A man wants to put a fence around a circular
flower bed. The fence is to be made of three
rounds of rope costing 45 per metre. Find the
cost of the rope if the diameter of the garden is
28 m.​

Answer 1

Answer:

Rs 11,880

Step-by-step explanation:

circumference of the given circle = 22/7 x Diameter

=> circumference = 22/7 x 28 = 22 x 4 = 88 m

given, fence is to be made by using three round of rope.

total fence required = 88m x 3 = 264 m

the cost of 1 metre of fence = Rs 45

so, the cost of 264 m of fence = Rs 45 x 264 = Rs 11,880
