<h3>Answer: (-8, 6)</h3>
====================================================
Work Shown:
B = (2,8) is the starting point
B' = (2,-8) after reflecting over the x axis. The y coordinate flips from positive to negative. The x coordinate stays where it is.
----------
(2,-8) is in the form (x,y) with x = 2 and y = -8
This shows (2,-8) translating or shifting to (-8,6) to get to the location for B''

Area of the shaded region is 540 – 65.25π.
Solution:
Length of the rectangle = 12 + 9 + 6 + 3 = 30 in
Width of the rectangle = 18 in
Radius of the larger circle () = 12 ÷ 2 = 6 in
Radius of the medium circle () = 9 ÷ 2 = 4.5 in
Radius of the smaller circle () = 6 ÷ 2 = 3 in
Area of the shaded region = Area of the rectangle – Area of the larger circle – Area of the medium circle – Area of the smaller circle
Area of the shaded region is 540 – 65.25π.
