It's time to show what you know! Individuals first review finding the area of polygons using the formulas from parallelograms to regular polygons. They then brush up on finding the area and circumference of circles, as well as reviewing...

Discuss all things round and round. Pupils review finding area and the circumference of circles and use them to solve problems. Next, they learn about central angles and their relationships to measures of arcs. Learners then find out how...

Slice off a piece of pi! A section of an extensive playlist on geometry develops the formula to find the length of an arc. Using the formula, the presentation works through examples finding the arc length, the radius, and the measure of...

Don't let your classes feel like they are going in circles. The video lesson shows pupils how to apply a formula to finding the length of an arc defined along a circle. The instructor uses three different examples to illustrate the...

An informative lesson begins with a concept video explaining how radians are figured. Then it offers videos of four progressively difficult guided practice problems.

There's no need to go to great lengths to learn about circles. Young mathematicians view a short YouTube video on how to find arc lengths of circles. The video covers a few examples highlighting the method of determining arc length in...

Video shows how to use integrals to write a formula for the perimeter of an area bounded on one side by a function. Includes showing how to derive the arc length formula. [5:41]

Video shows how to derive the arc length formula and how to use it to determine the total distance a particle traveled during a given time interval. [8:34]

Arc length for a curve.

In this video David shows how to relate the angular displacement to the arc length, angular velocity to the speed, and angular acceleration to the tangential acceleration. [14:36]

Video shows how to find an angle inscribed in a circle. [1:58]
