The volume of water in the vase is the difference of volume of cylinder and that of the marbles.
Vcylinder = πr²h = π(6 in)²(12 in) = 432π in³
Vmarbles = 9(4πr³/3) = 9(4π(3 in)³/3) = 324 π in³
The difference of the volumes is 108π in³.
To solve for Pi do the following:
C = 2Pi • r
C/2r = Pi
The solution would be Pi equals C over quantity 2 times r.
For this case we use the following definition:
sine (x) = (C.O) / (h)
Where,
x: angle
C.O: opposite leg
h: hypotenuse
Substituting values:
sine (C) = (C.O) / (h)
sine (C) = (AB) / (82)
We look for AB by Pythagorean theorem:
AB = root ((82) ^ 2 - (80) ^ 2)
AB = 18
Substituting:
sine (C) = (18) / (82)
Simplifying:
sine (C) = (9) / (41)
Answer:
the ratio is:
sine (C) = (9) / (41)

Answer:
Step-by-step explanation:
A positive parabola is one that has a + sign out front or no sign at all (and the positive is understood). A positive parabola opens like a cup with a bottom. Therefore, the positive parabola has a min value. A negative parabola opens upside down, like a mountain with a peak. Therefore, the negative parabola has a max value.
