.....I just found the circumference and multiplied that by the amount of revolutions then found the decimal amount of the mile it had traveled. Long story short, I got the same answer...looks all good to me! 0.4 ft. sounds right! (Don't ever forget the units. ;P) Hope that helps!

Woops! You had the units right...it asked for miles. My bad--good on ya for stickin' the landing on those units! http://web2.0calc.com/questions/posting.php?mode=reply&f=2&t=8763#

Why did you send me back to the same page. Don't you think that the world confuses me enough already??

'Twas an honest mistake! I tried to do a smiley, but I'm afraid that my inexperience prompted an unsavory display of my internet prowess, or lack thereof.

Katlina:

If the diameter of a wheel is 5 ft, about how many miles does the wheel
travel if it makes 134 revolutions? Use 2
7
2
for π. (Hint:1 mi 5280 ft.) It Also says round to the nearest tenth. II got .4 of a mile am I right?

what does use 272 mean?
anyway,

distance = (2*pi*r) / 5280 miles
=(2*pi*2.5) / 5280 miles
=0.4miles to the nearest mile. Good work
