One revolution = 2π radians

10 revolutions = 20π radians

33π/4 rad/min = 33π/4*(1/60) rad/s = 11π/80 rad/s

20π/(11π/80) = 80*20/11 = 1600/11 s

Answer: The answer is "145.5" seconds

Step-by-step explanation: I took the test. Also "matthew1756654" is technically correct. But the answer needs to be rounded to the nearest tenth. So 1600/11 is not the answer but one of the final steps. With 1600/11 = 145.45 then rounding to the nearest tenth making it 145.5

So please rate us both as correct.
