Two congruent figures, A and B, are shown on a coordinate plane below. Ay
V
Which of these reflection(s) map figure A onto figure B?
a reflection over the line y
a reflection over the line y--
a reflection over the line xo followed by a reflection over the line x = 0
a reflection over the line xo followed by a reflection over the line y = 0

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
