Answer:
A. 8 ft
B. 660 times
Step-by-step explanation:
A. Finding the circumference:
The formula for the circumference is
C = πD where D is the diameter
We are given D = 2.5, and to use π = 3.14, so plug those values in...
C = π(2.5) = (2.5)(3.14)
C = 7.85, which rounds to 8 (the nearest whole number)
B. How many times will it rotate in one mile.
Divide 5,280 by 8 to see how many times the tire will rotate (each time it rotates once the tire travels 8 ft)
5,280/8 = 660
Given :
There are 4,050 newspapers to be delivered in a certain area of town.
To Find :
If 18 newspaper carriers are all delivering the same number of papers, how many will each deliver.
Solution :
Let, total number of deliver are n.
Total newspaper, T = 4050 .
Number of news carriers, N = 18 .
So,

Therefore, each deliver will carry 225 newspapers.
Hence, this is the required solution.
