The Answer of The equations $x=\frac{9}{\pi} \cos (\pi / 180), y=\frac{9}{\pi} \sin (\pi / 180)$ describe the motion of a particle moving on a circle.Assume x and y are in miles and t is in days.What is the speed of the particle (in miles per day)when it passes through the point (-9/ $\pi$, 0)? Round to 3 decimal places.

The Equations x=9πcos⁡(π/180),y=9πsin⁡(π/180)x=\frac{9}{\pi} \cos (\pi / 180), y=\frac{9}{\pi} \sin (\pi / 180)x=π9​cos(π/180),y=π9​sin(π/180)

The Equations $x=\frac{9}{\pi} \cos (\pi / 180), y=\frac{9}{\pi} \sin (\pi / 180)$
