If a train runs on a circular track of radius 400 meters through all four sections of the park about how long is the part of the train track that runs through W class=

Respuesta :

The arc length is given by:

[tex]s=2\pi r(\frac{\theta}{360})[/tex]

In this case the radius is 400 m and the angle is 36°, plugging these values we have:

[tex]\begin{gathered} s=2\pi(400)(\frac{36}{360}) \\ s=251.33 \end{gathered}[/tex]

Therefore, the part of the train track that runs through water world is approximately 250 meters.
