The Diameter of a tire is 2.5ft. Use this measurement to answers parts a and b
A- find the circumference of the tire
B- about how many times will the tire have to rotate to travel 1 mile
A little tip should help
a. to find the circumference of the tire you need to multiply 3.14 by 2.5:
= 3.14 x 2.5
= 7.85 to round of it will be 8
b. to get the number of times the tire have to rotate to travel 1 mile:
1 mile = 5,280 ft
1 rotation is 7.85
5,280/7.85 = 672.611465
If that helps
wow
Thank you so much @BmS Btw @hello you have to divide it by 8.
thanks?
i got 672.611465, because 5280 divided by 7.85 = 672.611465. i got 7.85 by doing C= pi x 2.5. And since the mile/per feet was 5,280 feet. I divided that by the circumference.
For B part
To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference and d represents the diameter of the circle. In this case, the diameter of the tire is given as 2.5 feet.
A) To find the circumference of the tire, we can substitute the value of the diameter into the formula:
C = πd
C = π(2.5 ft)
So, the circumference of the tire is approximately C = 7.85 ft.
B) To determine how many times the tire will have to rotate to travel 1 mile, we need to convert the distance from miles to feet and then divide it by the circumference of the tire.
First, let's convert 1 mile to feet. Since 1 mile is equal to 5,280 feet, we have:
1 mile = 5,280 ft
Next, let's calculate the number of rotations by dividing the distance (in feet) by the circumference of the tire:
Number of rotations = Distance / Circumference
Number of rotations = 5,280 ft / 7.85 ft
By performing this calculation, we find that the tire will need to rotate approximately 672 times to travel 1 mile.
