1. Measure the length of the radius from your circle by selecting distance or length from the top menu, then selecting the two endpoints of a radius. Record your answer. 2. Calculate the circumference of the circle. Record your answer.
Calculate the arc length of the arc you constructed. Use the formula given.
Use the circle feature in the top menu to construct a circular arc. To do so, select the center point followed by the two points on the circle. The arc should be bold. Now measure the length of the arc you just constructed by selecting distance or length from the top menu, then clicking on the arc. How does this length compare with the length you calculated using the formula?
