Question 766117: I got this question for my homework. I just have to say that some terms in my question I couldn't put the real sign for it. The question in the brackets are an equation, and Pi is the term 3.14159265359.
The speed of a belt is given by the formula ' V = Pi dn ', where V is the speed of the belt in metres per minute, d the diameter of the pulley in metres and n the number of revolutions per minute. A machine belt runs at 400 metres per minute over a pulley running at 200 rpm. What is the diameter of the pulley?
Thank you and may I please have this answered as soon as possible.

V=πdn
d=V/πn
=0.64 m
