Area of the sector = 0.785 ft²
Explanation;
radius = 1 foot
θ = 90°
Formula for area of sector:
[tex]Area\text{ }of\text{ }a\text{ }sector=\theta/360\times\pi r^2[/tex][tex]\begin{gathered} \text{let }\pi\text{ = 3.14} \\ A\text{ rea = }\frac{90}{360}\times3.14\times1^2 \\ \end{gathered}[/tex][tex]\begin{gathered} \text{Area of sector }=\text{ 1/4 }\times\text{ 3.14} \\ \text{Area of the sector = 0.785 square f}eet \end{gathered}[/tex]
