Today JPaul and I discussed how to find the distance around a portion of a circle. We used the circumference formula C=2PiR to derive the formula for the arc length s=R(theta). We were given the radius of a circle and the angle measure and we used the formula to find the length of the intersected arc. JPaul found these problems to be easy. It became a bit more challenging when the angle measure was given in degrees. JPaul first changed it into radians, and then was able to apply the formula.
