Question

Each tire on your bicycle has a diameter of 26 inches.About how far will you travel when the tires make on complete revolution?

Answer 1

When the tires make one complete revolution, you'll travel the distance that is equal to one length of the wheel.

The length of the wheel is circumference of the circle with diameter of 26 in. The circumference can be found using formula

$l=\pi \cdot d,$ where d is diameter.

Thus,

$l=\pi \cdot d=\pi \cdot 26=26\pi\approx 26\cdot 3.14\approx 81.64\ in.$

Answer: you will travel about 81.64 in.

Answer 2

Circumference of a circle is an equation

c = (pie) x d or ........ c = 2(pie) × r
c = 3.14 × d or ...... c = 2(3.14) x r

d is the diameter and r is radius


c = (3.14) x 26
c = 81.64 in.
