The formula to find the area of a sector is:

A = \frac{degree}{360} \pi r^{2}

In this case:

Degree = 40

Radius = 8

^^^Plug these numbers into the formula given above

A = \frac{40}{360} \pi 8^{2}

Solve

A = \frac{1}{9}π8²

A =  \frac{1}{9}π64

A = \frac{64}{9}\pi

A = 7.1111111π

When rounded:

7.1π is the area of the sector

Hope this helped!

Answer:

<h2>7.1π</h2>

Step-by-step explanation:

Calculate what part of the angle 360° ​​is the given center angle 40°.

\dfrac{40}{360}=\dfrac{1}{9}

The same part of the area of the circle is the given sector.

The formula of an area of a circle:

A=\pi r^2

<em>r</em><em> - radius</em>

We have <em>r = 8.</em>

The area of a circle:

A_O=\pi(8^2)=64\pi

The area of the sector:

A=\dfrac{1}{9}A_O\to A=\dfrac{1}{9}(64\pi)=\dfrac{64}{9}\pi\approx7.1\pi
