Question

mrs corwin has a contractor install a new quarter circle window in her house like shown at right. what is the area of the window? use 3.14 pi. round to the nearest tenth

Answer 1

The area of a circle is given by:

`A=\pi r^2`

Since it is a quarter of the circle, the area is:

`\begin{gathered} A=\frac{\pi r^2_{}}{4} \\ where \\ r=7 \\ \pi=3.14 \\ so\colon \\ A=((3.14)(7^2))/(4) \\ A\approx38.5in^2 \end{gathered}`
