Find the area of a sector with a central angle of 140° and a diameter of 9.6 cm. Round to the nearest tenth.

olchik [2.2K]

Answer:

$A=28.1\ cm^2$

Step-by-step explanation:

The area of a circular sector with a central angle θ and radius r is given by:

$\displaystyle A=\frac{1}{2}r^2 \theta$

<em>Note</em>: The angle must be in radians.

We need to find both the radius and the angle in radians.

Diameter = 9.6 cm

Radius r=Diameter/2=4.8 cm

Angle in radians= Angle in degrees*π / 180

θ = 140*π / 180 = 2.4435 rad

Now we calculate the area:

$\displaystyle A=\frac{1}{2}(4.8)^2 2.4435$

$\boxed{A=28.1\ cm^2}$
