*Mastery Check. DO NOT ask for help. Find the area of the sector. Round your answer to the nearest tenth.

Juliette [100K]

The area of the sector is 472.6 ft²

<h3>Area of a Sector</h3>

For finding the area of the sector, you need apply the formula:

$A=\pi r^2* \frac{\alpha }{360}$ , where:

r= radius

α= central angle

The question gives:

r= radius= 19 ft

α= central angle = 150°

Thus, the area of the sector will be:

$A=\pi r^2* \frac{\alpha }{360}=\pi *19^2*\frac{150}{360} =472.6$
