A point on a wheel moves at  32π/9 radians per minute.

How many seconds are required for the point to complete 7 revolutions?

Enter your answer, rounded to the nearest tenth

 

 

I think it would be 236.3 seconds?

One revolution would be 2pi

 

7 revolutions would be   14 pi  R

 

Time in MINUTES   would be      14 pi R    /   32pi/9 rev/min    x  60 s/min  = 236.3 seconds
