MHB How many radians does the airplane propeller rotate in 190/3 pi seconds?

AI Thread Summary
The discussion centers on calculating the rotation of an airplane propeller in radians over a time period of 190/3 pi seconds. The initial inquiry questions the correctness of the radian usage, noting that 35 degrees appears small for the number of rotations. Responses confirm that the calculations are correct, suggesting that exact values should be provided for clarity. The recommended values include 190/3 pi radians and 7/2280 seconds. The conversation emphasizes the importance of precision in mathematical expressions.

OK, want to see if I am using the use of rad properly here
the answer seems very small. but 35 degrees isn't much for all the rotations.

Answer not in book so hope these are correct..

thanks ahead.

Looks good to me! (Sun)

Your answers are correct, but I would give exact values instead:

a) $$\frac{190}{3}\pi\text{ rad}$$

b) $$\frac{7}{2280}\text{ s}$$
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
