Calculating Circular Motion: Distance, Speed, Acceleration, and Period [SOLVED]

[SOLVED] Circular Motion

Homework Statement

A rotating fan completes 1170 revolutions every minute. Consider the tip of a blade, at a radius of 18.0 cm. (a) Through what distance does the tip move in one revolution? What are (b) the tip's speed and (c) the magnitude of its acceleration? (d) What is the period of the motion?

Homework Equations

I don't know exactly how to do these problems whatsoever because my professor didn't explain it too well. I know some circular motion formulas such as: a= the square root of ax squared + ay squared = (v squared/r) the square root of cos squared + sin squared = (v squared/r)= v squared/r.

The Attempt at a Solution

I don't even know where to start with this problem or know an equation that includes distance for part (a). It would be great if anyone knew how I could start this problem and if those equations seem right for this problem.

Surely you can attempt (a) at least? What is the circumference of a circle?

 

[shell4987]

Yes, I got part (a) to be 1.13 meters (113cm), but what formula do I use to compute both the speed and acceleration?

Actually, thank you very much for your help, I ended up trying a few things and figured out how to do this problem on my own.
