Oval running

Jan runs around the circumference of a circle with a diameter of 24 m. How many kilometers will he run if he goes around the circle four times?

Final Answer:

x =  0.3016 km

Step-by-step explanation:

$$\begin{gathered} d=24\text{m} \\ o=\pi \cdot d=3.1416\cdot 24\doteq 75.3982\text{m} \\ n=4 \\ {o}_2=n\cdot o=4\cdot 75.3982\doteq 301.5929\text{m} \\ x=o_2\to \text{km}=o_2:1000\text{km}=301.5929:1000\text{km}=0.302\text{km}=0.3016\text{km} \end{gathered}$$
