A=rx^{y}2 (4-\pi)

Work Step by Step

They area of the region can be found by subtracting the area of the square minus the area of the circle. Area of square = Length \times width = (2r)x^{y}2 Area of circle = \pirx^{y}2 Area of region= Area of square-Area of circle A= (2r)x^{y}2 - \pirx^{y}2 -Distribute the square to the 2 and r A=4rx^{y}2 - \pirx^{y}2 - rx^{y}2 is common so it is to be factored out A= rx^{y}2 (4-\pi)
