Answer
D: 132 ft
C= π2r
So, take pi and multiply that by two..
π2= 6.28
Now, take your radius and multiply it by 6.28.
21 x 6.28= 131.88
Round it two the nearest whole number, which is 132!
Hope this helps!
Answer:
Choice C.
Step-by-step explanation:
3rd degree means that the expression must have power of 3 as the highest power.
So, choice b is wrong since it has highest power of 8. All the other choices have highest power of 3.
Binomial means expression that has two terms.
So, choices d and a are wrong because they have 3 terms each.
So, choice C is correct answer and also it has constant as 8.

Answer:
The lower the volume, the higher the pressure.
Step-by-step explanation:
Volume and pressure are inverse to each other -- so the more pressure, the less volume, and vice versa. Think of it like this: if you were squished into a tiny room, there would be a lot of pressure on you, and not a lot of volume to move in!
You can also think of it numerically. The higher the V in that equation (the higher the denominator) the lower the p in the equation.
