Quadrant III

Work Step by Step

$\frac{16\pi}{3}$ radians It is a positive angle and obtained by rotating the terminal side counterclockwise $\frac{16\pi}{3}$ = $5\pi$ + $\frac{\pi}{3}$ radians. We use |$\frac{16\pi}{3}$| or $\frac{16\pi}{3}$ to determine the rotation. So $\frac{16\pi}{3}$ radians lies in quadrant III. Find the attachment.
