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. Hi Kyle, 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. Can you now see how to get the correct answer?Penny
