Answer:

[tex]A=16\pi\ units^{2}[/tex]

[tex]A=50.24\ units^{2}[/tex]

Step-by-step explanation:

we know that

The shape of the figure is a quarter of circle

so

The area of the figure is equal to the area of a circle divided by 4

[tex]A=\frac{1}{4}\pi r^{2}[/tex]

we have

[tex]r=8\ units[/tex]

substitute

[tex]A=\frac{1}{4}\pi (8)^{2}[/tex]

[tex]A=16\pi\ units^{2}[/tex] ----> exact answer

assume

[tex]\pi =3.14[/tex]

[tex]A=16(3.14)=50.24\ units^{2}[/tex] ----> decimal answer
