Length of an Arc and Area of a Sector
In this length of an arc and area of a sector worksheet, 10th graders solve and complete 12 different types of problems. First, they find the length of an arc in a circle with a given radius and central angle measure. Then, students find the area of a sector in a circle of a given radius and central angle measure.
NUMB3RS Activity: Meltdown
Young scholars investigate the relationship between the radius and area of circles that change size over time. They identify and interpret the puddle at a crime scene, that it is certain to be irregularly shaped and the floor would be neither smooth nor level.

Properties of Circles
Students study the properties of circles. In this circles instructional activity, students read a word problem about circles. Students watch a video about the activity and then practice drawing the circle solution to the problem. Students watch another video segment and discuss the methods in the video.

How Do You Find the Volume of a Sphere?
The formula for the volume of a sphere is volume equals four-thirds pi times the radius cubed. That's a mouth-full. But if you are given the radius value of the sphere, all you have to do is plug it in and do the arithmetic. Just remember to use the order of operations.
