1. The circumference is not 5 feet.

C = pi * d

5. C = 7.85

Then divide 5280 by 7.85
= 672.6

6. C = pi x d
C=3.14 x 2.5
C = 7.85

Then divide 5280 by 7.85
= 672.6 revolutions in one mile

13. A. YOU need to multiply 3.14 by 2.5
it equals 1.14 x 2.5
that equals 7.85
u have to round it so the final answer is 8

17. HERE'S HELP
1 mile = 5,280 feet
1 rotation is 7.85
5,280/7.85 = 672.611465

A. circumference is: 7.85 inches
B. it will rotate: 672 times
This is where you need to be.....

2.5 diameter times pi
gets you to 7.85 ft that is one rotation distance.
One miles is 5280 feet
you divide now your 7.85 into the 5280 and see how many times the tire will rotate .. the answer is that 672.611 number but the answer is 672
it will rotate 672 times to get a mile down the road because the circle is taking up seven inches to make a full rotation. get it? you're welcome!

20. The circumference is the line from the center of the circle to the edge of the circle, so if the hight of the circle is 2.5, we would have to divide it by 2 to get half the circle.
