Answer
b. 52.3
Explanation
The Area of a sector formula is
[tex]A=\frac{\theta}{360}\times\pi r^2[/tex]
Where A is the area of the sector,
θ = 60 degree and is the angle subtended at the center, and
r = 10 and is the radius of the sector
We shall use pi as 3.142
[tex]\begin{gathered} A=\frac{60}{360}\times3.142\times10^2 \\ A=\frac{1}{6}\times3.142\times100 \\ A=52.3 \\ \end{gathered}[/tex]
