a bicycle wheel rotates 5 times. The bicycle travels 37.94 feet in inches what is the diameter. Using 3.14 for pie.
Hi Ximena;
(37.94 feet)/(5 rotations)=7.588 feet
7.588 feet is the perimeter of the tire.
perimeter=(diameter)(3.14)
(7.588 feet)[(12 inch)/(1 foot)]=(diameter)(3.14)
The unit of feet/foot is in the numerator and denominator. It cancels...
(7.588 feet)[(12 inch)/(1 foot)]=(diameter)(3.14)
(7.588)(12 inch)=(diameter)(3.14)
91.056 inches=(diameter)(3.14)
Divide both sides by 3.14...
(91.056 inches)/(3.14)=[(diameter)(3.14)]/(3.14)
29. inches=diameter
