The linear speed of the pepperoni is 0.628 m/s. Its direction is tangential to the circle.
We know that;
v = rω
r = radius of the piece = 10 cm or 0.1 m
ω = angular velocity
We have to convert 60 revolutions per minute to radians per second
1 rev/min = 0.10472 rad/s
60 revolutions per minute = 60 rev/min × 0.10472 rad/s/1 rev/min
= 6.28 rad/s
v = 0.1 m × 6.28 rad/s
v = 0.628 m/s
The direction of this velocity is tangential to the circle.

The point obviously is in the 3rs quadrant
So
စ= tan^-1( y/x)-180
စ= -89.7°
In sound waves, the particles move in the same direction as the wave is moving, so you wouldn't be able to see them like ripples in the air, instead they make areas in the air where the particles are more squished together, and areas where the particles are further apart.
