Cylindrical and conical objects appear in modern architectural designs. Can you identify these objects in the music hall and surrounding buildings in the photograph? The area these objects cover are an important feature the architects had to consider.

 

In this lesson you explored these questions:

  • How can you determine the surface areas of cones and cylinders?
  • What are some everyday applications of the surface area of cones and cylinders?

Check your level of understanding of the materials covered in this lesson by completing “Lesson 5 Traffic Lights.”


If you select an amber or red traffic light in the multimedia piece, you will receive information about additional work you can complete to improve your understanding of the topics. Complete the suggested work before you proceed to the Lesson 5 Assignment. If you experience difficulty, contact your teacher before starting the Lesson 5 Assignment.

 

To answer these questions, you explored the surface area of cones and cylinders. You developed and applied the formulas for surface area for these objects in everyday contexts. Also, you extended your estimation skills to the surface areas of cylinders and cones.
