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
20 minutes* (1 hour/ 60 minutes)* (90 km/ 1 hour)= 30 km.
(Note that the units cancel out so you get the answer)
Final answer: 30 km~
