Circular track

The competitor runs on a circular track with a radius of 86 m. How many meters will he run in five rounds? (Solution and detailed procedure)

Correct answer:

x =  2702 m

Step-by-step explanation:

$$\begin{gathered} r=86\text{m} \\ n=5 \\ o=2\pi \cdot r=2\cdot 3.1416\cdot 86\doteq 540.3539\text{m} \\ x=n\cdot o=5\cdot 540.3539=2702\text{m} \end{gathered}$$
