Math 4 Unit 4, Lesson 1 Trigonometry: Ferris Wheel

The center of a Ferris wheel is 30 feet above the ground. The radius of the wheel is 25 feet. The wheel completes a full revolution every 20 seconds.[br][br]The height of the red chair changes over time.[br][br]1. Select Original Parameters and press the play button. Write down how the ferris wheel and the graph relate.[list][*]The height of the center of the wheel is 30 (25 foot radius plus 5 foot elevation above the ground)[br][/*][*]The radius of the wheel is 25 feet[br][/*][*]The time required for the wheel to complete one revolution is 20 seconds[/*][/list]2. Using your knowledge of trigonometric functions from Math 3, what is the equation describing the trace of the chair over time?[br]
