The linear speed of the object is the ratio between the measure of the arc it had traveled and the time. For the length of the arc,
2π x (20 m) x (0.2 rad/ 2π rad) = 4 meters
Divide this by the time, 10 s. Thus, the linear speed is equal to 0.4 m/s.

Since y has to be larger, the area is above the line.
Since the boundary is included (because of ≥ in stead of >) it should be drawn as a solid line.
Brings us to answer A, right?
See plot below.
7-c _< -3 put the line under the symbol
