Answer : The area of the sector not shaded is, 120π
Step-by-step explanation :
Given:
The angle of the sector = 60°
Radius of the circle = 12 unit
First we have to calculate the area of circle.
Formula used :
![\text{Area}=\pi * \text{Radius}^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/nmyqb3v8yndxcdqp0wp8dw0x3mr8dzc6of.png)
Now put all the given values in this formula, we get:
![\text{Area}=\pi * 12^2=144\pi](https://img.qammunity.org/2021/formulas/mathematics/middle-school/dsb1sxma6c4lrfhhpg4t4zrv45tsdlkwjt.png)
Now we have to calculate the area of sector that are shaded.
Formula used :
![\text{Area of the sector}=(\theta)/(360^(\circ))* \text{Area of the circle}](https://img.qammunity.org/2021/formulas/mathematics/middle-school/xxypzvlnpgkqe6ili323gnvtxigj35r138.png)
Now put all the given values in this formula, we get:
![\text{Area of the sector}=(60^(\circ))/(360^(\circ))* 144\pi\\\\=(1)/(6)* 144\pi\\\\=24\pi](https://img.qammunity.org/2021/formulas/mathematics/middle-school/jr3oztx2hmm9p0n9wop9igg40158jxd4if.png)
Now we have to calculate the area of sector that is not shaded.
Area of the sector not shaded = 144π - 24π = 120π
Therefore, the area of the sector not shaded is, 120π
