Question

Find the area of the blue sector. Use 3.14 for pi and round to the nearest hundredth.

Answer 1

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
