The diameter of a tire is 2.5 ft. Use this measurement to answer parts a and b. Show all work to receive full credit.
I need help with part B
About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)
Answered by Ms. Sue
C = pi * d
C = 3.14 * 2.5
C = ??? feet

Divide 5,280 by the circumference.



Answered by henry2,
Circumference = pi * d = 3.14 * 2.5 = 7.85 ft.
1 mile = 5,280 ft.
5,280ft * 1rev/7.85ft =

be more clear pls thank you
Answered by trustmeplease
i got 672.611465, because 5280 divided by 7.85 = 672.611465. i got 7.85 by doing C= pi x 2.5. And since the mile/per feet was 5,280 feet. I divided that by the circumference. IDK if this is correct so please correct me if i'm wrong.

Answered by Smart person
Because many people are having trouble let me try to break it down!

To find the circumference you use the formula C = d x pi (pi being 3.14)

The next problem might sound tricky, but trust me it's very simple, All you do is divide 5,280 by the circumference, now if you get a big number, which you will, then you just round (you just found the circumference all you do in plug it in)
I hope this helps in some way!!

2.5*3.14 = 7.85
5,280 ÷ 7.85 = 672.611464968
