We use direct proportionality:
360⁰......Pi×R² (full circle)
120⁰.......x
x=120×pi×R²/360=pi×R²/3
x=pi×4²/3=16.76mi²
A=3×pi cm², for an angle of 2×pi/3=120⁰
In a similar way we compute the area of the full circle:
360.........x
120..........3×pi
x=3×pi×360/120=9×pi=3²×pi.
Thus the radius is 3cm.
Answer:

Step-by-step explanation:
What divided by what equals 0? What divided by what equals 0? Specifically, what positive whole number (X) can you divide by another positive whole number (Y) to get 0? The answer is infinite.
Answer: 8327
Step-by-step explanation:
The arithmetic mean of a data is given by :_

Given : For the most recent seven years, the U.S. Department of Education reported the following number of bachelor's degrees awarded in computer science: 4,033; 5,652; 6,407; 7,201; 8,719; 11,154; 15,121.
Then, the annual arithmetic mean number of degrees awarded will be :-

Hence, the annual arithmetic mean number of degrees awarded = 8327
Slope is -1/3 !! hope this helps :)
[-1,1] if you want interval notation but its just between negative one and 1
