Question

Margaret's bicycle tires are 26 inches in diameter. How far will her bike travel every time the wheel completes one revolution? (This is the same as the circumference of the wheel.)

Answer 1

Margaret's bicycle tires have a diameter of 26 inches.

Each time her wheels completes one revolution, then the distance covered would be equivalent to the circumference of the wheel. To calculate the circumference, we would use the following formula;

$\begin{gathered} \text{Circumference}=2\pi r \\ \text{Where the variables are;} \\ r=13\text{ inches (}\frac{diameter}{2}) \\ \pi=3.14 \end{gathered}$

Hence, the distance travelled for each revolution would be;

$\begin{gathered} \text{Circumference}=2\times3.14\times13 \\ \text{Circumference}=81.64 \end{gathered}$

ANSWER:

The distance covered by Margaret's bike for every revolution is

$81.64\text{ inches}$
