A thin wire is bent into the shape of a semicircle x^2+y^2=4 x>0
If the linear density is 3, find the mass of the wire.
Anyone have a clue how to tackle this problem?
Thanks for your help

ok ok you win, lol (duh about the 18pi! thats what happens when 20 vector calc problems are running through your head.)
(180/360)*((2(pi)*2)=6.28
6.28*3=18.84
6*pi=18.84
Thanks for your help, I really appreciate it!
