"One rotation" would be the circumference of the wheel, which is
C = 2*pi*r, or (here) C = 2*pi*(8 inches) = 16*pi inches.
1 ft
Convert this to feet: 16*pi inches times ---------------
12 inches
Here "inches" cancels out and you are left with (4/3)pi ft.
So, one rotation of the wheel moves you and your bike forward (4/3)pi ft.
Divide this into 700 feet:
700 ft 2100
------------- = --------- rotations = 525 rotations (answer)
(4/3) pi ft 4
Let us say that this number is n
Then we could say:
<em><u>n - 9</u></em>
Answer:
-4 < x ≤ 9
Step-by-step explanation:
1.6 is = to 1 6/10 = 1 3/5
so 1.6 in simplest form is 1 3/5
Hope this helps! :D
Answer:
