For a circle of radius 2 feet, find the arc length s subtended by a central angle of 54 degrees.

R = 2 ft; α = 54°
s = ( r π α ) / 180°
s = ( 2 π 54° ) / 180°
s = 108° π / 180°
s = 0.6 π ft
or: s = 0.6 · 3.14 = 1.884 ft

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
