My name is Kyle and I am a student.

This is a secondary level question from the June 1999 NYS Regents exam.

Here's the question:

In circle O, a central angle of 3 radians intercepts an arc of 27 meters. Find the number of meters in the length of the radius.

I can give you an approximation immediately. There are pi radians in 180^o and pi is approximately 3.14, so 27 meters gets you almost half way around the circle. Hence the correct answer is a little more than 2*27 = 54 meters.
