HELP ASAP!!
The fiqure shown was created by placing the vertage of a square within the circle. What is the area of the shaded region? Use 3.14 to approximate pi, remember to answer using cm^2
Please show work!

The area of the shaded region is  

Step-by-step explanation:

we know that

The area of the shaded region is the area outside the square and inside the circle

so

The shaded area is equal to the area of circle minus the area of the square

we have

----> the radius is half the diameter

---> the length side of the square

substitute

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

what is the model?
