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)
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.
Ok, I'm confused. Like really confused, this makes no sense. 😭
C = pi * d
C = 3.14 * 2.5
C = ??? feet
Divide 5,280 by the circumference.
Circumference = pi * d = 3.14 * 2.5 = 7.85 ft.
1 mile = 5,280 ft.
5,280ft * 1rev/7.85ft =
