It asks me to convert 3 radians into revolutions showing 3 decimal places.
rad/2*pie = no of revolutions

You can put this solution on YOUR website!
3/(2*pi) = 0.47746...
---------------
When you enter 3/2*(pi) into your calculator
it divides the 3 by 2 gettiing 1.5 then it mul
multiplies 1.5 and pi to get 4.7123...
-----------
That shows you how important parentheses are.
