Answer:
16π m2
Step-by-step explanation:
The area of a sector (A) is given by:

Where
is the angle of the sector
r is the radius of the circle
<em>We can see that the angle of the sector is 90, and the radius of the circle is 8. Plugging these into the formula, we get:</em>

The area is 16π m2
+2+(-3)+(-1)+4(-5)+(-3) ok so first 2 is positive and 3 is negative there both different signs so u subtract +2+(-3)=-1+(-1)=0+4=4+(-5)=-1+(-3)=-4 your answer is 4
