In this arcs and chords worksheet, 10th graders solve 7 different types of problems related to identifying arcs and chords in a circle. First, they find the measure of each arc to the nearest tenth, if O is the center point. Then, students find the length of a radius in a circle where the chord is 16 inches long and 6 inches from the center. They also find the distance from the center of the circle to the chord.
