this guy helps me in ochem, and now in physics?!

i love you

[gachibaka2]

this helps alot but can you help/ explain to me this question:

An electric hoist is being used to lift a 300lb container. The diameter od the drum

( of the hoist) is 16in, and the container must be raised 50 feet.

*what is the cercumference of the drum?

*how many revolutions willl it take to rise the container 50 feet?

*how many radians must the drum rotate?

*how many degrees must the drum rotate?

please help me out if you can.

thanks
