How much can be placed on a circular serving tray that has a diameter of 18 in? leave answer in terms of pi.

A=π*.
A=π*81
A≈254.47

That doesn't account for the third dimension, nor the walls of the tray.
That's the area of the given face of the tray.

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
