<PRE><B>Question 146678</B>
1. if a flywheel is 1 m in diameter and if a belt over the wheel is rotating at the rate of 1000 m per minute, find the number of revolutions of the wheel per minute.

------------------
The circumference of the wheel is (pi)d or (pi)*1 = (pi) meters
--------------
#of revolutions = 1000 m/ pi m = 318.31
