Answer:

Step-by-step explanation:
An arc measure of 20 degrees corresponds to a central angle of 20 degrees.
Area of sector of circle

where n = central angle of circle, and r = radius



256.
The coefficient of just the y term would be 256 because the entire expanded equation looks like this:
y^4+16y^3+96y^2+256y+256
Answer:
Step-by-step explanation:
3x - 3y = 3(x-y)
First, what's 3 to the power of 8?
Then what's 3 to the power of 10
Now subtract them by each other for your answer
