A wheel has a radius of 3.7 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°, 30 rad, and 30 rev, respectively?(adsbygoogle = window.adsbygoogle || []).push({});

30° m

30 rad m

30 rev m

I really need help on this. I dont even understand what im suppose to do because I dont really understand the question and from what the teacher told us had nothing or in anyway how to solve an equation like this.

for the first equation i tried using this

deltaTheta = w_initial*t + 1/2alphat^2 but then i realize i dont know what alpha or t is. so thats when i thought w_initial is 0 so

deltaTheta = 1/2alpha*t^2 then i got this s = theta*r which will give me time in second but not sure.

any help would be great and very helpful to my studying.
