640
Step-by-step explanation:
Expanding the binomial :
r⁵ - 40r⁴ + 640r³ - 5120r² + 20480r - 32768
The coefficient of r³ is 640
The formula for the area of a circle is PI x radius^2.
To find the area of the sector, you would multiply the area by the ratio of the the sector angle over 360.
The formula would become PI x r^2 x 30/360.
The 2nd choice is correct.
