Answer:
8.6 km
Step-by-step explanation:
The circumference of a circle is given in terms of its radius as ...
C = 2πr
Then the radius can be found from the circumference using ...
r = C/(2π)
Filling in the given values, we find the radius to be ...
r = (54 km)/(2·2.14) = (54 km)/6.28 ≈ 8.59873 km
The radius is about 8.6 km.
Answer:
280m
Step-by-step explanation:
Work rate would be (210m)/(45people)(60days)=7/90 m/(people)(day)
7/90 m/(people)(day) * 72people * 50days =280m
1.41/100 = 0.0141 * 15 = 0.21
$0.21
