The figure is made up of four identical squares of side length 12 inches. A quadrant is drawn inside each square. Find the total area of the shaded parts of the figure. Use 3.14 as an approximation for π.

164.16 in²

Step-by-step explanation:

Area of the shaded region = [4 quarter circles - 4*triangular regions]

                                             = 4*(1/4)*π (12)²- 4*(12*12/2)

                                             = 3.14(144) - 2(144)  

                                             = 164.16 in²

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
