**Question description**

#### Objective

- Determine the number of rotations of a circle of a specified size it takes to cover a given distance
**Circles :** - Answer the following questions and turn in:

- How do you find the area of a circle?
- How do you find the circumference of a circle?
- What information do you need in order to find the area or circumference of a circle?
- To determine the number of full rotations your tires complete before you need to switch the front and back tires, will you be working with area or circumference?
- Measure the circumference of the tires of three different vehicles. Vehicles can include cars, bikes, scooters, tractors, etc.
- Determine the number of full rotations the tires of each of the vehicles will complete in 10,000 miles.
- Choose one of the vehicles and keep track of how far you travel in that vehicle for a week. Calculate the average daily number of rotations made by the tires.
- Use your data to predict when you will need to switch the front and back tires.
- a table containing the circumferences of the tires of three vehicles
- clearly labeled calculations showing how you determined the number of rotations each of the vehicles’ tires will complete in 10,000 miles
- data showing distance traveled in a week
- clearly labeled calculations showing how you found the average daily number of rotations
- a prediction for when you will need to switch the front and back tires and an explanation of your prediction
- a paragraph explaining what would happen to the number of rotations if your tires’ circumference increased by 20%
- a paragraph explaining what would happen to the number of rotations if your tires’ circumference decreased by 20%
