A railroad toy is laid out in circular form. What diameter should be used if the track is to change direction by 60� in a distance of 30 cm?
-------
The entire angle around the track is 6*60 degrees = 360 degrees
------
Therefore the entire distance around the track is 6*30 = 180 cm
------
Perimeter = pi*(diameter)
180 = pi*diameter
----
diameter = 180/pi is approximately 57.3 cm
