If an object travels in a circle 32pi/5 radians, at what degree measure is it, relative to where it started?

a) 1052°

b) 144°

c) 72°

d) 98.6°

I got 1152° but there is no option for the answer, what did I wrong?

32PI/5 rad* 180 deg/PI= 32/5*180=32*36

You are right.

32/5 = 6 2/5

so we have gone 6 pi radians + 2/5 of a radian

but 6 pi radians is 3 whole circles

so we end up at (2/5)pi radian

(2/5)pi(180/pi) = 72 degrees

Why is 32/5 = 6 2/5?

Jake, division

5 ( 6 + 2/5)/5 = (30 + 2)/5 = 32/5

Well mine is pretty cooked mentally.
