Answer
Grazing Area = 339.43 square units
Step-by-step explanation
The area of the grazing are is the area of the sector outside the shaded square.
The area of a sector is given as
![\text{Area = }(\theta)/(360\degree)*\pi r^2](https://img.qammunity.org/2023/formulas/mathematics/college/3um7p1cxd33dgup1vuwn3cbobxfx74bndv.png)
where
θ = Angle subtended at the center of the circle by the sector = 360° - 90° = 270°
π = pi = 3.142
r = radius of the circle = 12 units
![\begin{gathered} \text{Area = }(\theta)/(360\degree)*\pi r^2 \\ \text{Area = }(270\degree)/(360\degree)*\pi*12^2 \\ \text{Area = 339.43 square units} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/owj0o50jv2r1im13xfu1v6sfs1e7jzmkkb.png)
