Answer 1

Given data:

The given radius of the circular window is,

`r=3(1)/(2)\text{ ft}`

The expression for the area of the window is,

`A=\pi r^2`

Substitute the given value in the above expression.

`\begin{gathered} A=(22)/(7)(3.5ft)^2 \\ =38.5ft^2 \end{gathered}`

Thus, the area of window is 38.5 ft^2.
