Answer:
$ 1508.57 and please give brainliest
Step-by-step explanation:
The road around the park = 3 m wide,
and the circumference of the park = 132 m,
We have to find the cost of fencing
the outer boundary,
the rate = $10 per m
Step-by-step explanation:
As we know that the circumference
of a circle = 2 × 22÷7 × radius
2 × 22÷7 × radius = 132 m,
44 × radius = 132 m × 7,
44 × radius = 924 m,
radius = 924 ÷ 44 m
So, radius = 21 m ( smaller circle )
radius = 21 m + 3 m ( larger circle )
= 24 m
Usually, we fence on the borders means it's
the circumference of the larger circle
= 2 × 22÷7 × radius
= 44÷7 × 24 m
= 1056÷7 m
= 150.85 m
cost of fencing = $ 10/m
total cost = 150.85 × $ 10
= $ 1508.57
