Ch 13: Perimeter, Area & Volume

About This Chapter

Prepare for the ELM exam's questions on perimeter, area and volume. The video lessons and quizzes provided here present the information in an engaging and easy-to-follow format.

Perimeter, Area and Volume - Chapter Summary

This chapter's lessons demonstrate the formulas used to calculate the perimeter, area and volume of quadrilaterals and circles, as well as of more complicated shapes. You will learn to figure the perimeter of a shape even when you are missing some information. By the end of this chapter, you will be familiar with methods of determining the following:

  • Perimeter of triangles and rectangles
  • Area and circumference of circles
  • Volume of cylinders, cones and spheres
  • Volume of pyramids and prisms
  • Area of complex figures
  • Perimeter of quadrilaterals, irregular and combined shapes

Expert instructors will guide you through these topics, using real-life examples to reinforce the concepts. You can check what you've learned with the self-assessment quizzes at the end of each video, and links to key topics make it easy to go back and re-watch areas that you need to review.

Perimeter, Area and Volume Chapter Objectives

Many incoming students to the California State University system are required to take the ELM exam in order to determine placement in mathematics classes. The ELM consists of 50 multiple-choice questions, and you are given 90 minutes to complete it. The test is divided into three sections, and the questions relating to the topics covered in this chapter are found in the Geometry section, which makes up about 30% of the total test. One of the test's objectives calls for finding the perimeter, area and volume of circles, triangles, quadrilaterals, cylinders, rectangular parallelepipeds and combinations of these figures.
