\begin{cases}
r=radius\\
\theta =angle\ in\\
\qquad degrees\\

What is the coefficient of x2 in the expansion of (x + 2)3?
wolverine [178]
One way is that you can just factor it out: (x+2)(x+2)(x+2)
For the first pair, you get x^2+4x+4.
Then do (x^2+4x+4)*(x+2)
That will be x^3+6x^2+12x+8
So the answer is 6

puteri [66]
The area of the sector will also be 70/360
Sector area = 70/360 • pir^2

A= 112/9 • pi
A= 39.1 inch^2
