11.4 Practice B: Circumference and Arc Length
9th - 12th
In this circumference and arc length worksheet, students determine the circumference, radius, and arc length of circles. They find the area of a shaded region within a circle. Students determine the probability that a randomly chosen point in a figure will lie within a shaded region. This four-page worksheet contains approximately 40 multi-step problems. Each page contains a different topic and may be assigned independently.
