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
