Respuesta :

Given:

Given that the radius of the circle is 12 inches.

The angle of the shaded sector is 210°

We need to determine the area of the shaded sector.

Area of the shaded sector:

The area of the shaded sector can be determined using the formula,

[tex]Area =(\frac{\theta}{360}) \pi r^2[/tex]

Substituting [tex]\theta=210[/tex] and r = 12, we get;

[tex]Area =(\frac{210}{360}) (3.142)(12)^2[/tex]

Simplifying, we get;

[tex]Area =(\frac{210}{360}) (3.142)(144)[/tex]

[tex]Area =263.9 \ in^2[/tex]

Thus, the area of the shaded sector is 263.9 square inches.

Hence, Option c is the correct answer.
