Question 974206
<pre>
Suppose an object is whirling around in a circle of radius r meters.

Every time the object makes 1 revolution, it travels through 1 circumference of
the circle.

The formula for the circumference of the circle is 2<font face="symbol">p</font>r.

So calculate the circumference of the circle it's whirling around in and then
multiply the RPMs by that.
