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

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
