The shaded region is the portion inside x2+y2=R2{“version”:”1.1″,”math”:”x2+y2=R2″} in the first quadrant. Set up and evaluate an integral that gives the area of this region.

In a carnival ride, passengers stand with their backs against the wall of a cylinder. The cylinder is set into rotation and the floor is lowered away from the passengers, but they remain stuck against the wall of the cylinder. For a cylinder with a 2.0-m radius, what is the minimum speed that the passengers can have so they do not fall if the coefficient of static friction between the passengers and the wall is 0.25?
