Make a hypothesis! We will compare 3 different sized tires; 18 inches, 22 inches, and 30 inches. If you compare the amount of rotations needed to travel a mile between the 3 tires of different sizes, which tire do you think makes the most rotations to drive one mile.
a. the 18 inch tires
b. the 22 inch tires
c. the 30 inch tires

to determine the distance traveled by a car wheel based on rotations made will you be working with area or circumference?

a. circumference
b. area

what is the circumstance of a tire with a diameter of 18 in ?
tips:c= n*d or c=2*n*r

a. 113.1
b.28.3
c.254.5
d.56.5
