Question

What is the approximate length of the track in miles

Answer 1

Step-by-step explanation

Opposite sides are 5 miles each and for each semicircle we have:

`(2\pi *(1)/(2))/(2)=(\pi)/(2)\text{ miles}`

Then the lenght of the track is:

`5+5+(\pi)/(2)+(\pi)/(2)=10+\pi`

Approximately 13.1416 miles
