In the diagram below, what is the approximate length of the minor arc DE?
Check the final answer first, then review the worked steps.
Step-by-step solution
The length of the minor arc DE is calculated using the formula: Arc Length = (central angle / 360°) 2 pi radius. Given the central angle is 36° and the radius is 10 cm, the arc length is (36/360) 2 pi 10 = 0.1 20 pi = 2 * pi \approx 6.28 cm.
Answer
6.3 cm
