Answer: the answer is 0.03
Step-by-step explanation:
0.9030 > 0.8736
0.9 > 0.8
so your first option is correct
The formula to find the area of a sector is:
A = ![\frac{degree}{360} \pi r^{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bdegree%7D%7B360%7D%20%5Cpi%20r%5E%7B2%7D)
In this case:
Degree = 40
Radius = 8
^^^Plug these numbers into the formula given above
A = ![\frac{40}{360} \pi 8^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B360%7D%20%5Cpi%208%5E%7B2%7D)
Solve
A =
π8²
A =
π64
A = ![\frac{64}{9}\pi](https://tex.z-dn.net/?f=%5Cfrac%7B64%7D%7B9%7D%5Cpi)
A = 7.1111111π
When rounded:
7.1π is the area of the sector
