Quick!

aabc has vertices at (-4,4), (0,0) and (-5,-2). find the coordinates of points a, b and c after a reflection across the y- axis.

point a’:
point b’:
point c’:

The Y axis, would be when y = 0.

Point B is located on the Y -axis, so the coordinates would be the same.

For A and C the Y coordinate would remain the same and the X coordinate would be  the opposite ( from negative to positive).

A (-4,4) would become (4,4)

B (0,0) would stay the same so would be (0,0)

C (-5,-2) would become (5,-2)

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
