Given, the diameter of the apple pie, D=15 cm.
The radius of the apple pie is,
[tex]\begin{gathered} r=\frac{D}{2} \\ =\frac{15\text{ cm}}{2} \\ =7.5\text{ cm} \end{gathered}[/tex]The area of the pie is,
[tex]\begin{gathered} A=\pi r^2 \\ =\pi(7.5)^2 \\ =176.7cm^2 \end{gathered}[/tex]Therefore, the area of the apple pie is 176.7 cm^2.
