A circular track has an inside cirumference of 220m. If the width of track is 3.5m, find its outer circumference.
Answers: 1
![r=\frac{L_{c}}{2*\pi } \\\\r = \frac{220}{2*\pi }\\\\r = 35.01 [m]](/tpl/images/0927/8143/113ec.png)
![L_{c} = 2*\pi *38.51 \\L_{c} = 242 [m]](/tpl/images/0927/8143/89bd0.png)
