Try \(2\pi r\) for one rotation.|dw:1396663931798:dw|
OpenStudy (anonymous):
so if i try this for one rotation so 2pi r = 2x(22/7)x1200 = 7542.86
OpenStudy (anonymous):
I tried to multiply this number by 40 but the answer is not included in the choices. I must have done something wrong
OpenStudy (anonymous):
these are the choices A) 48,000 B) 150,796 C) 225,000 D) 250,435
OpenStudy (doc.brown):
Wait, is Ï there on purpose? What's Ï?
