A wheel has a radius of .30m. It rotates 185 times before it stops.
How far did the vehicle travel?

Here is the sollution:During one rotation the wheel covers the distance of its circumference that can be counted with formula:[tex]x=2*π*r[/tex]in which r is radius, then:[tex]x=2*3,14*0.30m=1,884m[/tex]We know that it rotates 185 times so you need to multiply the wheel's circumference by 185 to get total distance (D):[tex]D=185*x=185*1,884m=348,54m[/tex]The answer is that the vehicle traveled 348,54 m far.

The circumference of any circle is  (2 pi) x (radius) .185 times the circumference of a circle is  (185) x (2 pi) x (radius) .If the wheel doesn't slip, then it rolls (185) x (2 pi) x (0.3 m) = 348.72 m (rounded)
