Question

Andrew runs around a circular track each morning. The diameter of the track is approximately mile. Approximately how far does Andrew run if he completes 11 laps around the track?The picture is just a Visual

Answer 1

The diameter of the track is d = 1/4 miles.

Detemine the distance run by Andrew in one lap.

`\begin{gathered} D=\pi d \\ =\pi\cdot(1)/(4) \\ =0.7854 \end{gathered}`

Determine the diatnce covered in 11 laps.

`\begin{gathered} D^(\prime)=11\cdot0.7854 \\ =8.6394 \\ \approx8.6 \end{gathered}`

So answer is 8.6 miles.
