How do you convert 13 revolutions into radians and degrees?
One revolution is 360 degrees or 2 pi radians ( full circle) So 13 rev = 13 x 60 degrees or 13 x 6.28 radians
Convert -320 degrees to radians?
-5.58505361 radians.
Suppose that a disk rotates through five revolutions in 4 seconds. What is its displacements in radians in this time?
To find the displacement in radians, you can use the fact that one complete revolution corresponds to (2\pi) radians. If the disk rotates through five revolutions, the total displacement is (5 \times 2\pi = 10\pi) radians. Therefore, the displacement of the disk in 4 seconds is (10\pi) radians.
What is cosine of 42?
In radians: cos(42) = - 0.399965315 ---------------------- In degrees: cos(42) = 0.7431448255 ----------------------
