Answer:
The area of blue sector is 25.64 in²
Step-by-step explanation:
In the given figure, we need to find the area of blue section whose central angle is 60°
Formula:
\(\text{Area of sector}= \dfrac{\theta}{360^\circ}\times \pi r^2\)
Radius of circle (r)=7 in
\(\theta = 60^\circ\)
Substitute the value into formula and find area of sector.
\(\text{Area of blue sector}= \dfrac{60}{360}\times3.14\times 7^2\)
\(\text{Area of blue sector}= 25.643\approx 25.64\text{ in}^2\)
Hence, The area of blue sector is 25.64 in²
