Question

The radius of a circle garden is 56 m.what would it cost to put a 4-round fence around this garden at a rate of 40 rupees per metre

Answer 1

Answer:

Step-by-step explanation:

Given radius of circular garden (r) = 56 m.

Therefore, circumference of garden = 2$\pi$r

= 2 × (22/7) × 56

= 352 m

Given that fencing is to be done in 4 rounds

Therefore, total fencing to be done = circumference × 4 = 352 × 4 = 1408 m.

Now, given rate of fencing = Rs. 40 /m

Therefore, total cost of fencing = 1408 × 40 = Rs. 56320
