Consider a circle with radius r=6 and a central of 0= 3pi/4.
What is the exact and length of the arc intersected by 0? Note, the exact answer must contain pie and must be reduced to lowest terms.

The first one minimumi hope my answer you.

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
