The formula for the area of wedge is,
[tex]A=\frac{\theta}{360}\cdot\pi(\frac{d}{2})^2[/tex]
Determine the area of wedge with theta = 45 degree and d = 18 in.
[tex]\begin{gathered} A=\frac{45}{360}\cdot\pi(\frac{18}{2})^2 \\ =0.125\pi\cdot81 \\ =31.80 \\ \approx31.8 \end{gathered}[/tex]
So area of wedge is 31.8 in^2.
