11.4 Practice B: Circumference and Arc Length

9th - 12th
246 Downloads

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.

Area of Circles and Probability

Students investigate the area of squares and circles. In this geometry lesson plan, students calculate the area and probability of simple events. They work on a laptop using Safari.

How on Earth?

The equator and longitudinal lines make interesting circles to study in terms of arc length. Using Google Earth or a globe, pupils research specific questions about size and distance. This a great activity to bring some real-world application into your classroom. 

Circles

In this geometry instructional activity, students identify the different properties of a circle. The measure and calculate the length of the diameter and circumference. There are 15 question on 4 worksheets.

Properties of Arcs, Lengths and Chords

Students differentiate between the different properties of arcs, arc lengths, chords, and chord lengths. In this circles instructional activity, students calculate the arc length of a given circle, and find the measure of the inscribed angles of a circle and a polygon.

Solving Problems Involving Chords, Radii, Tangents, Secants, and Arcs Within the Same Circle

Tenth graders explore the concept of circles.  In this circles activity, 10th graders discuss settings in their lives where they encounter circles.  Students work through problems in groups involving finding lengths of diameters, secants, tangents, arcs, and radii of circles and semi-circles.

Measuring Angles-Grade 11

Eleventh graders discover the relationship between radian measure and arc length.  In this Algebra II lesson, the inquiry approach provdes for hands on activities and the use of technology to accommodate various learning styles.  Includes pre- and post-assessment.

Geometric Probablitiy:  Spinners and Dartboards

Sstudents explore and analyze the properties of geometric areas.  In this geometry lesson plan, sstudents use technology to simulate spinners and dartboards in order to fing areas of circles and sectors of circles and compare and contrast theoretical and experimental data.

Measuring the Earth

Students identify types of arcs and angles in a circle, find the measure of arcs and angles, and solve real world problems involving lengths of segments in circles, lengths, and areas.

Arc Lengths and Sector Areas

Students explore the concept of arc length.  In this arc length lesson, students examine a picture of a Ferris wheel in terms of its sector areas and arc lengths.  Students try to find the sector area and arc length of their Ferris wheel in groups.  Students present their results to the class.

Areas of Polygons, Arc Length, and Area Sectors

Math scholars explore the concept of area. In this area lesson, learners find the area of cardboard squares and circles that they have created. They use their cardboard constructions to find midpoint, area of sectors, arc length and other measurable attributes of a circle.
