The diameter of a tire is 2.5 ft. What is the circumference of the tire? About how many times will thee tire have to rotate to travel in 1 mile? 5280 ft.
A. 5 ft?
B. 1,056ft???
tbh i kinda dont care if i get this one wrong i just wanna finish my homework
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
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!
C = 7.85
Then divide 5280 by 7.85
= 672.6
I gotta agree with you on this one mate
Guys WTF just explain please!!
B. 1 mile = 5,280 feet
1 rotation is 7.85
5,280/7.85 = 672.611465
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
