Given that,
Radius of the circle, r = 8.91 cm
Angle, [tex]\theta=81^{\circ}[/tex]
To find,
The area of minor sector.
Solution,
The formula for the area of minor sector is given by the formula as follows :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{81}{360}\times \pi \times (8.91)^2\\\\A=56.11\ \text{cm}^2[/tex]
So, the area of the shaded sector is [tex]56.11\ \text{cm}^2[/tex].
