Answer:
71.45
Step-by-step explanation:
The area of a circle is [tex]\pi r^2[/tex]
Approximating pi as 3.14:
[tex]A=3.14(8^2)=200.96[/tex]
This is the area of the whole circle.
Given a sector of 128 degrees, that is [tex]\frac{128}{360}[/tex] of the total circle.
So our sector area is
[tex]\boxed{\frac{128}{360}(200.96)=71.45 \ \mbox{to 2dp}}[/tex]
