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, in the box.

 

I got 236.3, could someone double check this? Thank!

32pi/9  rad/min =  32pi / (9*60)   rad/sec = .186 rad sec    

 

7 revs is 14 pi radinas

 

14 pi rad  / .186 rad/sec = 236.25  seconds
