9-80.
1. Sketch a unit circle with an angle that measures 6 radians. Homework Help ✎

1. Approximately how many degrees is 6 radians?

2. Using only your diagram, estimate the sine of 6 radians.

Notice that 2π radians ≈ 2(3.14) ≈ 6.27.
So it's a little less than 360°.

$\frac{6}{2 \pi} = \frac{x}{360}$

6 radians ≈ 344°

sin(6) = −0.3
