Answer:
The radius is approx. 7.5
Let me know if it helps or if I got anything wrong!
Step-by-step explanation:
To find the circumference, you need to multiply the diameter by pi (3.14)
And for vice versa, just divide.
Since we don't know the diameter nor radius, we need to divide the Circumference (C) by pi (3.14)
47/3.14=14.968
Which is rounded up to 15.
We have now found the diameter.
We also know that the radius is half of the diameter
15/2=7.5
Answer:
5 days
Step-by-step explanation:
This problem is an inverse proportion case. Having two variables: number of workers and time (in days); when we increase the number of workers, the time needed decreases; vice versa. Therefore, we can use the multiplication method: (workers * time) will always stay constant.
Let's say the time (in days) needed by the eleven workers is t,
5*20 = (3*10) + (14*t)
100 = 30+14t
70 = 14t
5 = t
It will take the eleven-workers 5 more days to finish the road.
