Answer:

27.9cm^2

Step-by-step explanation:

The <u>total area</u> of the circle is given by:

a=\pi r^2

where \pi is a constant \pi=3.1416

and r is the radius: r=8cm

Thus the total area of this circle is:

a=(3.1416)(8cm)^2\\a=(3.1416)(64cm^2)\\a=201.06cm^2

We want only the area of the arc that measures 50°. For this we must remember that the arc of the total circle is 360°.

Thus, we want 50° out of the 360° degrees in the circle. For this, we divide the total area by 360 and then we multiply by 50:

\frac{201.06cm^2}{360}(50)=0.5585cm^2(50)=27.9cm^2

the area of the sector to the nearest tenth is 27.9cm^2
