on a coordinate grid, point p is at (5, 2) and point r is at (−3, −4). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s?
q(−5, 2), s(3, −4)
q(−5, −2), s(3, 4)
q(5, −2), s(−3, 4)
q(−5, 2), s(−3, 4)

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)
