Answer:
B 14.13 
Step-by-step explanation:
Volume of cone is 
soo it would be:
3.14(1.5)^2(6/3)
=3.14(2.25)(2)
=7.065(2)
=14.13
Answer:
41.667 to the nearest thousandth.
Step-by-step explanation:
z = kx/y where k is the constant of proportionality.
Inserting the given values:
66.666666666667 = k*20/6
20k = 6*66.666666666667
k = 6*66.666666666667 / 20
= 20
So the equation of variation is z = 20x /y
When x = 25 and y = 12:
z = 20*25/12
= 41.666666666667.
Start by taking away 22.36 from each side so that you are left with 4.73c = 42.57
And then divide each side by 4.73 so you will get c = 9
The correct answer is x = 6
