Given data:
The given diameter is d=10.5 in.
The expression for the area of the circle is,
[tex]A=\frac{\pi}{4}(d)^2[/tex]Substitute the given values in the above expression.
[tex]\begin{gathered} A=\frac{3.14}{4}(10.5)^2 \\ =86.54625 \\ \approx86.5 \end{gathered}[/tex]Thus, the area of the circle is 86.5.
