How do vehicles turn so smoothly? When a car makes a U-turn, the outer wheel travels farther than does the inner wheel. So why doesn’t the car feel jerky?

In this lesson, students calculate the circumferences of circles to determine how far vehicles travel during a turn and explore the engineering that allows cars to turn so smoothly.

Students will

  • Calculate the circumference of a circle
  • Model with geometry to solve real-world problems

Before you begin

Students should be familiar with the formula of the circumference of a circle.
